技术领域 Technical field
本发明属于土木工程结构和机械结构减振技术领域, 具体涉及一种用于控制 交通运输工具、 机器设备运转等原因引发的结构振动的调谐质量减振器。 The invention belongs to the technical field of civil engineering structure and mechanical structure vibration reduction, and particularly relates to a tuned mass damper for controlling structural vibration caused by transportation tools, machine equipment and the like.
背景技术 Background technique
近年来, 我国轨道交通飞速发展, 给人们提供了快捷、 安全的出行方式的同 时, 其产生的振动和噪声问题也严重影响了周边居民的生活质量, 危及周边建筑 安全, 并且使轨道本身的稳定性、 安全性和使用寿命也受到影响。 In recent years, China's rail transit has developed rapidly, providing people with a fast and safe way of travel. At the same time, the vibration and noise problems caused by it have seriously affected the quality of life of surrounding residents, endangered the safety of surrounding buildings, and stabilized the track itself. Sex, safety and service life are also affected.
随着城市建设的发展, 各种高层、 超高层建筑和细高结构、 大跨度建筑物日 益增多, 同时, 城市交通网络越来越发达, 各种大跨度的机场登机桥、人行天桥、 港口栈桥等桥梁结构得到了广泛的应用,为人们的出行带来了极大的便利。但是, 此类细高建筑物及桥梁虽然强度和刚度比较容易满足设计要求, 其竖向振动的频 率却普便都比较低(例如大跨度人行天桥的竖向频率通常只有 2赫兹左右) , 在 强风激励或行人、 车辆等动载作用下容易发生共振, 给行人带来不舒服的感觉, 造成结构物自身结构损坏, 甚至严重威胁到人和车辆的安全。 如何防止这类大跨 度、 低频结构物发生破坏性共振成为工程建设中不得不着手解决的现实问题。 实 践证明, 调谐质量减振器(也有文献中称质量调谐阻尼器, 或称质量调谐减振器, 本文中也简称减振器或 TMD )是一种有效的振动控制装置,将它的固有频率调整 到接近结构的自振频率,然后安装在结构上。 当结构受到激振力干扰发生振动时, 引起调谐质量减振器的共振, 利用调谐质量的振动惯性力反作用于结构本身, 从 而抵消激振力, 达到减小结构反应的目的, 例如申请号为 200410087664.2之中国 专利所公布的定向垂直可调式调谐质量减振器。 但是, 现有调谐质量减振器产品 中弹性元件主要依赖螺旋钢弹簧, 弹性元件的品种比较单一; 另一方面, 弹性元 件直接与外部环境接触, 容易产生锈蚀、 落入杂物等问题, 影响产品的减振性能; 再有, 现有的调谐质量减振器多附加在建筑结构上, 受建筑结构的加工误差及设 计变更影响较大, 有时还会影响建筑结构的美观; 第四, 受现有产品结构和弹性 元件特点的限制, 产品的固有频率较低, 不适于控制 15Hz以上的高频振动, 适
用范围受限。 With the development of urban construction, various high-rise, super-tall buildings and high-rise structures and large-span buildings are increasing. At the same time, urban transportation networks are becoming more and more developed, and various large-span airport boarding bridges, pedestrian bridges, and ports Bridge structures such as trestles have been widely used, bringing great convenience to people's travel. However, although the strength and rigidity of such high-rise buildings and bridges are relatively easy to meet the design requirements, the frequency of vertical vibration is relatively low (for example, the vertical frequency of a long-span pedestrian bridge is usually only about 2 Hz). Strong winds or pedestrians, vehicles and other dynamic loads are prone to resonance, causing uncomfortable feelings to pedestrians, causing structural damage to the structure itself, and even seriously threatening the safety of people and vehicles. How to prevent such large-span, low-frequency structures from destructive resonance has become a practical problem that must be solved in engineering construction. It has been proved that the tuned mass damper (also referred to in the literature as a mass tuned damper, or mass tuned damper, also referred to herein as a damper or TMD) is an effective vibration control device that will have its natural frequency. Adjust to the natural frequency of the structure and then install it on the structure. When the structure is excited by the exciting force, the resonance of the tuned mass damper is caused, and the vibration inertial force of the tuned mass is used to counteract the structure itself, thereby canceling the exciting force and achieving the purpose of reducing the structural reaction, for example, the application number is The directional vertically adjustable tunable mass damper disclosed in the Chinese Patent No. 200410087664.2. However, in the existing tuned mass damper products, the elastic components mainly rely on spiral steel springs, and the elastic components are relatively simple; on the other hand, the elastic components are directly in contact with the external environment, which is prone to rust, falling into debris, etc. The vibration damping performance of the product; in addition, the existing tuned mass damper is attached to the building structure, which is greatly affected by the processing error and design change of the building structure, and sometimes affects the aesthetic appearance of the building structure; The limitations of the existing product structure and the characteristics of the elastic components, the natural frequency of the product is low, and it is not suitable for controlling high-frequency vibration above 15 Hz. The scope of use is limited.

与现有技术相比, 本发明带有框架的调谐质量减振器, 将质量块和弹性元件 构成的质量——弹簧***设置在联接框架内, 其具有如下优点:
( 1 )联接框架对质量块、 弹性元件和阻尼元件形成有效的保护, 耐候性好, 防止水、 油、 灰尘进入, 特别当使用高分子弹性材料时, 防止臭氧和紫外线损坏 高分子材料, 弹性材料不易发生老化, 可大大延长产品的使用寿命; Compared with the prior art, the framed tuned mass damper of the present invention has the mass-spring system formed by the mass and the elastic element disposed in the coupling frame, which has the following advantages: (1) The joint frame effectively protects the mass, the elastic element and the damping element, has good weather resistance, prevents the ingress of water, oil and dust, especially when using the polymer elastic material, prevents ozone and ultraviolet rays from damaging the polymer material, and elasticity. The material is not prone to aging, which can greatly extend the service life of the product;
( 2 )除了质量调谐减振外, 当质量块和联接框架大于一个模态频率的 1/2波 长时, 质量块和联结框架会对弹性元件及阻尼元件产生约束作用, 二者之间的相 对变形会剪切二者之间的阻尼材料, 实现额外的剪切变形耗能, 因此减振效果更 显著; (2) In addition to mass tuning and damping, when the mass and the joint frame are larger than 1/2 wavelength of a modal frequency, the mass and the joint frame will restrain the elastic element and the damping element, and the relative relationship between the two The deformation will shear the damping material between the two to achieve additional shear deformation energy consumption, so the damping effect is more significant;
( 3 )本发明带有框架的调谐质量减振器在结构上实现突破, 对弹性元件的 限制更少, 弹性元件的选材范围广, 因此其适用的频率更宽; (3) The tuned mass damper with frame of the present invention achieves a breakthrough in structure, has fewer restrictions on elastic members, and has a wide selection range of elastic members, so that the frequency of application thereof is wider;

( 6 )对质量块与联接框架之间设置的弹性元件实施预压缩后, 一方面即使 构成弹性元件的材料开裂、 有内部裂缝, 弹性元件的刚度和调谐质量减振器的工 作频率不会发生变化; 另一方面, 当用于控制高频振动时, 质量块的振幅较小, 经预压缩后, 弹性元件的刚度呈线性变化, 更容易准确设计调控; 第三, 由于实 施了预紧, 弹性材料万一开裂, 质量块也不会脱落, 安全可靠。 (6) After pre-compression of the elastic member disposed between the mass and the coupling frame, on the one hand, even if the material constituting the elastic member is cracked and there is internal crack, the rigidity of the elastic member and the operating frequency of the tuned mass damper do not occur. On the other hand, when used to control high-frequency vibration, the amplitude of the mass is small. After pre-compression, the stiffness of the elastic element changes linearly, which makes it easier to accurately design and control. Third, due to the pre-tightening, If the elastic material is cracked, the mass will not fall off, which is safe and reliable.
综上, 本发明带有框架的调谐质量减振器的结构简单, 减振降噪效果好, 性 能稳定, 适用频域范围更广, 使用寿命长, 对建筑结构的外观影响小, 性价比十 分优越, 可以广泛应用于控制交通运输工具、 机器设备运转等原因引发的结构振 动, 其市场应用前景十分广阔。 In summary, the tuned mass damper with frame of the invention has simple structure, good vibration and noise reduction effect, stable performance, wide frequency domain range, long service life, small influence on the appearance of the building structure, and excellent cost performance. It can be widely used to control structural vibration caused by transportation tools, machinery and equipment, etc., and its market application prospect is very broad.

Specifically, the elastic member 4 is disposed between the upper and lower surfaces of the mass 3 and the cavity wall of the vibration absorbing cavity 100. The coupling frame 2 is made of an aluminum alloy material, and the elastic member 4 is made of a rubber material, because the rubber material has good damping characteristics. It is a commonly used elastic solid damping material, so that the elastic member 4 is also a damping member, and the mass 3 is an iron block, wherein the elastic member 4 is fixedly coupled to the mass 3 and the coupling frame 2 by a vulcanization process, respectively. In order to increase the reliability of the connection between the elastic member and the coupling frame and the mass block, a connection reinforcing structure is respectively disposed on a part of the mating surface of the vibration absorbing cavity wall and the elastic member, and a part matching surface of the mass block and the elastic member, respectively.

下面以应用于建筑结构为例对本发明的应用进行说明。 应用时, 可以直接将 本发明带有框架的调谐质量减振器直接固定在建筑结构表面。 建筑结构受到外部 激励下发生振动时, 质量块与弹性元件构成的质量——弹簧调谐***, 产生反作 用力作功耗能使得建筑结构的振动迅速得以衰减, 趋于静止, 此外, 联接框架、 弹性体及质量块之间还构成约束阻尼耗能结构, 当质量块和联接框架大于一个模 态频率的 1/2波长时, 质量块压缩弹性元件向联接框架移动的过程中, 质量块和 联结框架会对橡胶材料产生约束作用, 二者之间的相对变形会剪切二者之间的橡 胶材料, 实现额外的剪切变形耗能, 因此可以进一步提高减振耗能的效果, 实现 延长建筑结构使用寿命的目的。 需要指出的是, 本例中, 虽然仅在质量块 3上、 下表面与联接框架 1之间设置了弹性元件 4, 但由于弹性元件 4在横向也具有一 定的弹性, 因此本例所述本发明带有框架的调谐质量减振器可以实现同时控制建 筑结构在垂向及横向的振动。 实际应用中, 可以通过优化弹性元件 4的弹性以及 质量块 3的总重量, 实现对不同频率振动的控制。 除桥梁等建筑结构外, 本发明 带有框架的调谐质量减振器还可以应用于轨道交通、大型回转设备的振动控制中, 例如, 可以将本发明带有框架的调谐质量减振器固定设置在钢轨的非工作表面, 用于控制钢轨的振动; 也可以设置在摆放大型回转设备的楼板上, 用于控制楼板 的共振, 都能实现很好的效果。 The application of the present invention will be described below by taking an example of application to a building structure. When applied, the framed tuned mass damper of the present invention can be directly attached to the surface of the building structure. When the building structure is vibrated by external excitation, the mass of the mass and the elastic element - the spring tuning system, generates a reaction force for power consumption, which can quickly attenuate the vibration of the building structure and tend to be stationary. In addition, the joint frame and the elastomer And the mass block also constitutes a constrained damping energy dissipation structure. When the mass block and the coupling frame are larger than 1/2 wavelength of one mode frequency, the mass block compresses the elastic element to move to the coupling frame, and the mass block and the coupling frame will The rubber material has a restraining effect, and the relative deformation between the two will shear the rubber material between the two to realize additional shear deformation energy consumption, so that the vibration damping energy consumption can be further improved, and the use of the building structure can be extended. The purpose of life. It should be noted that, in this example, although the elastic member 4 is disposed only between the upper and lower surfaces of the mass 3 and the coupling frame 1, since the elastic member 4 has a certain elasticity in the lateral direction, the present embodiment is described. The invention of the tuned mass damper with frame can simultaneously control the vertical and lateral vibration of the building structure. In practical applications, the control of vibration at different frequencies can be achieved by optimizing the elasticity of the elastic member 4 and the total weight of the mass 3. In addition to building structures such as bridges, the framed tuned mass damper of the present invention can also be applied to vibration control of rail transit and large-scale rotary equipment. For example, the tuned mass damper with frame of the present invention can be fixedly set. On the non-working surface of the rail, it is used to control the vibration of the rail; it can also be set on the floor of the pendulum-amplified rotary equipment to control the resonance of the floor, which can achieve good results.

In addition, depending on the specific materials of the elastic member, the mass and the coupling frame, it is also possible to provide the connection reinforcing structure only on the mating surface of the coupling frame and the elastic member, or to strengthen the connection only on the mating surface of the mass and the elastic member. Structure, the specific structure of the surface convex-concave structure may be various forms such as protrusions, pits, continuous ribs or continuous grooves, and the cross-sectional shape of the surface convex-concave structure may be rectangular, trapezoidal, circular, triangular, T-shaped, etc. In addition to the surface relief structure already mentioned, the connection reinforcement structure can also be a structural form such as a surface knurling structure or a surface squeezing structure, and can also achieve a good effect, and cannot be--illustrated, only The description in words is within the scope of protection claimed in the present invention.
与现有技术相比, 本发明带有框架的调谐质量减振器, 将质量块和弹性元件 构成的质量——弹簧***设置在联接框架内, 其具有如下优点: Compared with the prior art, the framed tuned mass damper of the present invention has the mass-spring system of the mass and the elastic element disposed in the coupling frame, which has the following advantages:

( 2 )除了质量调谐减振外, 当质量块和联接框架大于一个模态频率的 1/2波 长时, 质量块和联结框架会对弹性元件及阻尼元件产生约束作用, 二者之间的相 对变形会剪切二者之间的阻尼材料, 实现额外的剪切变形耗能, 因此减振效果更 显著; (2) In addition to mass tuning and damping, when the mass and the joint frame are larger than 1/2 wavelength of a modal frequency, the mass and the joint frame will restrain the elastic element and the damping element, and the relative relationship between the two The deformation will shear the damping material between the two to achieve additional shear deformation energy consumption, so the damping effect is more significant;
( 3 )本发明带有框架的调谐质量减振器在结构上实现突破, 对弹性元件的 限制更少,弹性元件的选材范围广,因此其适用的频率更宽,可以适用于控制 15Hz 以上的高频振动; (3) The tuned mass damper with frame of the present invention achieves a breakthrough in structure, has fewer restrictions on elastic components, and has a wide selection range of elastic components, so that the frequency of application is wider, and it can be applied to control above 15 Hz.

Small, after pre-compression, the stiffness of the elastic component always changes linearly, which makes it easier to accurately design and control. Thirdly, due to the pre-tightening, the elastic material will not fall off if it is cracked, which is safe and reliable. In the present invention, the elastic member may be pre-tensioned or not pre-tensioned, and the limitation or fixation of the elastic member may be considered when not pre-tightening. These features are applicable to all embodiments of the present invention, and are described herein, not in the following embodiments. Repeat one by one. In general, when controlling high-frequency vibration, the elastic element must be pre-tensioned. When controlling low-frequency vibration, the elastic element may not be pre-tensioned. In practical applications, whether the elastic element can be selected according to the characteristics of the required control vibration frequency Implement pre-compression. In summary, the tuned mass damper with frame of the invention has simple structure, good vibration and noise reduction performance, low cost, long service life and excellent cost performance, which is beneficial to delaying the wear of the building structure and prolonging the structure of the building. The service life is very broad.
特别要指出的是, 本发明中的弹性元件除了如图 2中所示沿吸振腔 100的轴 向连续设置以外, 还可以如图 3所示, 沿吸振腔 100的轴向间隔设置, 只要优化 好弹性元件的刚度参数, 都可以实现同样的效果, 间隔设置弹性元件有利于缩减 弹性元件的材料投入, 进而降低产品成本, 也在本发明要求的保护范围之中。 In particular, the elastic members of the present invention may be disposed along the axial direction of the vibration absorbing chamber 100 as shown in FIG. 3, in addition to being continuously disposed along the axial direction of the vibration absorbing chamber 100 as shown in FIG. The same effect can be achieved by the stiffness parameters of the elastic members. The spacing of the elastic members helps to reduce the material input of the elastic members, thereby reducing the product cost, and is also within the scope of protection claimed in the present invention.
实施例二 Embodiment 2
如图 4所示本发明带有框架的调谐质量减振器, 与实施例一的区别在于, 弹 性元件 4设置在质量块 3左右侧面与吸振腔 100腔壁表面之间, 联接框架 2由玻 璃钢材料制成, 弹性元件 4由高阻尼弹性聚氨酯材料制成, 质量块 3由钢材料制 成, 其中, 弹性元件 4通过化学粘接工艺分别与质量块 3和吸振腔 100腔壁固连 在一起。 为了增加弹性元件与联接框架及质量块之间连接的可靠性, 在联接框架 与弹性元件的配合表面以及质量块与弹性元件的配合表面上分别设有连接加强结 构, 所述的连接加强结构具体为吸振腔 100腔壁相应表面上设置的表面拉毛结构 32及质量块 3相应表面上设置的表面滚花结构 33。由于弹性元件 4釆用的高阻尼 弹性聚氨酯材料也具有良好的阻尼特性, 也是常用的弹性固体阻尼材料之一, 因 此弹性元件 4同时也是阻尼元件。 此外, 弹性元件 4在与质量块 3及联接框架 2 进行装配时被预压缩, 处于预压缩状态, 并且弹性元件 4的预压缩位移大于质量 块 3工作时相对于吸振腔 100腔壁的振幅。 As shown in FIG. 4, the framed tuned mass damper of the present invention is different from the first embodiment in that the elastic member 4 is disposed between the left and right sides of the mass 3 and the cavity wall surface of the absorbing chamber 100, and the coupling frame 2 is made of FRP. Made of material, the elastic member 4 is made of a highly damped elastic polyurethane material, and the mass 3 is made of a steel material, wherein the elastic member 4 is fixedly bonded to the mass 3 and the cavity wall of the vibration absorbing chamber 100 by a chemical bonding process. . In order to increase the reliability of the connection between the elastic member and the coupling frame and the mass, a joint reinforcing surface is respectively arranged on the mating surface of the joint frame and the elastic member and the mating surface of the mass and the elastic member, and the joint reinforcing structure is specifically The surface burring structure 32 disposed on the corresponding surface of the cavity wall of the absorbing chamber 100 and the surface knurling structure 33 disposed on the corresponding surface of the mass 3 are provided. Since the high damping elastic polyurethane material used for the elastic member 4 also has good damping characteristics, it is also one of the commonly used elastic solid damping materials, and therefore the elastic member 4 is also a damping member. Further, the elastic member 4 is pre-compressed when assembled with the mass 3 and the coupling frame 2, in a pre-compressed state, and the pre-compression displacement of the elastic member 4 is larger than the amplitude of the cavity 3 relative to the wall of the vibration-absorbing chamber 100 when the mass 3 is in operation.
本例所述的技术方案的应用方法及优点与实施例一基本相同, 在此不再重 复。 需要指出的是, 本例所述本发明带有框架的调谐质量减振器中, 仅在质量块
3左右侧面与联接框架 1之间设置了弹性元件 4,因此本例所述本发明带有框架的 调谐质量减振器主要用于控制建筑结构在横向的振动, 当然其对垂向振动也有一 定的控制作用。 与实施例一相比, 本例所述技术方案中, 因为对弹性元件实施了 预压缩, 即使弹性元件中的高阻尼弹性聚氨酯材料开裂, 有内部裂缝, 弹性元件 的刚度和本发明带有框架的调谐质量减振器的工作频率不会发生变化, 其减振性 能更加稳定可靠。 当然, 基于实施例一中所述的技术原理, 本例所述本发明带有 框架的调谐质量减振器的装配过程中, 也可以不对质量块与联接框架之间设置的 弹性元件实施预压缩, 也可以实现同样的技术效果, 也在本发明要求的保护范围 之中, 实际应用中, 可以根据所需控制结构振动频率的特点, 选择是否对弹性元 件实施预压缩。 The application methods and advantages of the technical solutions in this example are basically the same as those in the first embodiment, and are not repeated here. It should be noted that in the tuned mass damper with frame of the present invention described in this example, only in the mass The elastic element 4 is disposed between the left and right sides and the coupling frame 1. Therefore, the tuned mass damper with the frame of the present invention is mainly used for controlling the vibration of the building structure in the lateral direction, and of course, it also has a certain vertical vibration. Control role. Compared with the first embodiment, in the technical solution of the present embodiment, since the elastic member is pre-compressed, even if the high-damping elastic polyurethane material in the elastic member is cracked, there is internal crack, the rigidity of the elastic member, and the frame of the present invention. The operating frequency of the tuned mass damper does not change, and its damping performance is more stable and reliable. Of course, based on the technical principle described in the first embodiment, in the assembly process of the framed tuned mass damper of the present invention, the elastic component disposed between the mass and the coupling frame may not be pre-compressed. The same technical effect can also be achieved, and also within the scope of protection required by the present invention. In practical applications, whether or not to pre-compress the elastic element can be selected according to the characteristics of the vibration frequency required to control the structure.
实际应用中, 可以通过优化弹性元件 4的弹性以及质量块 3的总重量, 实现 对不同频率振动的控制。 使用时, 可以针对建筑结构的多个主要振动频率, 将控 制相应振动频率的本发明带有框架的调谐质量减振器交替设置在建筑结构中即 可。 In practical applications, the control of vibration at different frequencies can be achieved by optimizing the elasticity of the elastic member 4 and the total weight of the mass 3. In use, the framed tuned mass damper of the present invention that controls the corresponding vibration frequency can be alternately placed in the building structure for a plurality of primary vibration frequencies of the building structure.
实施例三 Embodiment 3
如图 5所示本发明带有框架的调谐质量减振器, 与实施例一的区别在于, 联 接框架 2由钢材制成, 弹性元件 4釆用金属弹簧, 本例中具体为螺旋钢弹簧, 螺 旋钢弹簧的两端分别焊接固定在联接框架 2及质量块 3上。 此外, 为确保使用过 程中, 弹性元件 4始终对质量块 3形成有效的支承, 弹性元件 4在与质量块 3及 联接框架 2进行装配时被预压缩, 处于预压缩状态, 并且弹性元件 4的预压缩位 移大于质量块 3工作时相对于吸振腔 100腔壁的振幅。 As shown in FIG. 5, the framed tuned mass damper of the present invention is different from the first embodiment in that the coupling frame 2 is made of steel, and the elastic member 4 is made of a metal spring, in this case, a spiral steel spring. Both ends of the spiral steel spring are respectively welded and fixed on the joint frame 2 and the mass block 3. Furthermore, in order to ensure that the elastic element 4 always forms an effective support for the mass 3 during use, the elastic element 4 is pre-compressed when assembled with the mass 3 and the coupling frame 2, in a pre-compressed state, and the elastic element 4 The pre-compression displacement is greater than the amplitude of the cavity 3 relative to the chamber wall of the vibration-absorbing chamber 100 when it is in operation.
本例所述技术方案与实施例一的应用方法相同, 在此不再重复。 此外, 与实 施例一相比, 本例所述本发明带有框架的调谐质量减振器还具有如下优点: 由于 釆用螺旋钢弹簧作为弹性元件, 螺旋钢弹簧除了在垂向具有艮好的弹性外, 其在 横向也具有良好的弹性, 因此通过控制螺旋钢弹簧的垂向刚度和横向刚度之间的 关系, 本例所述本发明带有框架的调谐质量减振器可以同时控制建筑结构的横向 及垂向振动, 其物理性能受温湿度等环境因素影响小, 减振性能更高效稳定, 使 用寿命更长。 另外, 可以作为弹性元件的金属弹簧除了已经提到的金属螺旋弹簧 夕卜, 还可以是碟簧或板簧, 都可以实现很好的效果, 都在本发明要求的保护范围 之中。 当然,为了保证弹性元件在使用过程中始终对质量块保持有效的弹性支承, 对于单独釆用金属弹簧构成的弹性元件, 在本发明加工制造的过程中, 优选的,
弹性元件与质量块及联结框架进行组装时实施预压缩, 这一点也适用于本发明其 他应用金属弹簧构成弹性元件的技术方案, 在此一并给予说明。 The technical solution in this example is the same as the application method in the first embodiment, and is not repeated here. In addition, compared with the first embodiment, the framed tuned mass damper of the present invention has the following advantages: Since the spiral steel spring is used as the elastic member, the spiral steel spring has a good shape in the vertical direction. In addition to elasticity, it also has good elasticity in the lateral direction. Therefore, by controlling the relationship between the vertical stiffness and the lateral stiffness of the spiral steel spring, the framed tuned mass damper of the present invention can simultaneously control the building structure. The lateral and vertical vibration, its physical properties are less affected by environmental factors such as temperature and humidity, the vibration damping performance is more efficient and stable, and the service life is longer. In addition, the metal spring which can be used as the elastic member can achieve a good effect in addition to the metal spiral spring already mentioned, which can also be a disc spring or a leaf spring, and is all within the scope of protection required by the present invention. Of course, in order to ensure that the elastic member maintains an effective elastic support for the mass during use, the elastic member composed of a metal spring alone is preferably used in the process of manufacturing the present invention. The pre-compression is carried out when the elastic member is assembled with the mass and the coupling frame. This is also applicable to the technical solution of the other application of the metal spring of the present invention to constitute the elastic member, which will be described together.
当然, 本发明也不排斥弹性元件未被预压缩的技术方案, 根据不同需要, 弹 性元件也可以不预压缩, 例如本例中可以将金属螺旋弹簧两端分别与质量块及联 接框架焊接固定在一起, 不对弹性元件实施预压缩。 一般来说,控制高频振动时, 必须对弹性元件实施预紧,控制低频振动时, 弹性元件可以不预紧, 实际应用中, 可以根据所需控制结构振动频率的特点, 选择是否对弹性元件实施预压缩。 Of course, the present invention does not exclude the technical solution that the elastic element is not pre-compressed. According to different needs, the elastic element may not be pre-compressed. For example, in this example, the two ends of the metal coil spring may be welded to the mass block and the coupling frame respectively. Together, the elastic element is not pre-compressed. In general, when controlling high-frequency vibration, the elastic element must be pre-tensioned. When controlling low-frequency vibration, the elastic element can be not pre-tensioned. In practical applications, whether the elastic element can be selected according to the characteristics of the required control vibration frequency Implement pre-compression.

如图 19和图 20所示本发明带有框架的调谐质量减振器, 与图 5所示带有框 架的调谐质量减振器的区别在于,联接框架 2由钢板制成,联接框架的吸振腔 100 中还设有阻尼元件 65, 所述阻尼元件 65由液体阻尼材料构成, 吸振腔 100两端 开口处设有密封件 66, 密封件 66由钢板制成, 密封件 66与联接框架两端; t早接固 连在一起, 将吸振腔 100完全封闭, 液体阻尼材料填充在质量块 3与吸振腔 100 腔壁之间的部分空隙中。 19 and 20, the framed tuned mass damper of the present invention is different from the framed tuned mass damper shown in FIG. 5 in that the coupling frame 2 is made of steel plate and the coupling frame is absorbing. The cavity 100 is further provided with a damping element 65. The damping element 65 is composed of a liquid damping material. The opening of the vibration absorption cavity 100 is provided with a sealing member 66. The sealing member 66 is made of steel plate, and the sealing member 66 and the two ends of the coupling frame are provided. The t-weaving cavity 100 is completely closed, and the liquid damping material is filled in a part of the gap between the mass 3 and the cavity wall of the absorbing cavity 100.
本例所述本发明带有框架的调谐质量减振器的应用方法与实施例一完全相 同, 在此不再重复。 以应用于建筑结构为例, 由于吸振腔 100中增设了液体阻尼 材料构成的阻尼元件 65, 质量块 3吸收建筑结构振动能量发生位移时, 液体阻尼 材料会产生一个阻碍质量块移动的反力,从而将质量块的能量迅速消耗掉。 因此, 不但能够使建筑结构的振动能量迅速衰减, 还可以抑制弹性元件 4的共振, 使弹 性元件 4迅速恢复静止, 从而提高弹性元件的疲劳寿命, 进而延长本发明产品的 使用寿命。 The application method of the tuned mass damper with frame in the present invention is exactly the same as that of the first embodiment, and will not be repeated here. For example, when applied to a building structure, a damping element 65 composed of a liquid damping material is added to the vibration absorbing chamber 100. When the mass 3 absorbs the vibration energy of the building structure, the liquid damping material generates a reaction force that hinders the movement of the mass. Thereby the energy of the mass is quickly consumed. Therefore, not only the vibration energy of the building structure can be rapidly attenuated, but also the resonance of the elastic member 4 can be suppressed, and the elastic member 4 can be quickly restored to a standstill, thereby improving the fatigue life of the elastic member and further prolonging the service life of the product of the present invention.

In practical applications, it is possible to select whether to pre-compress the elastic element according to the characteristics of the required vibration frequency of the control structure.

与实施例十四相比, 由于质量块 3表面设置了多条凸棱 67, 质量块 3与液体 阻尼材料构成的阻尼元件 65的有效接触面积更大,液体阻尼材料对质量块产生的 阻力也就更大, 因此耗能更快, 减振效果也更好。 Compared with the fourteenth embodiment, since the surface of the mass 3 is provided with a plurality of ribs 67, the effective contact area of the mass 3 and the damping element 65 composed of the liquid damping material is larger, and the resistance of the liquid damping material to the mass is also It is even bigger, so it consumes more energy and the vibration damping effect is better.
基于本例所述的技术原理, 凸棱 67 的截面形状也可以是圓弧形、 矩形、 梯 形等多种形状。 此外, 扰流凸凹结构可以多种多样, 例如, 也可以如图 23所示, 扰流凸凹结构由质量块 3表面设置的多条凹槽 68构成; 或者如图 24所示, 扰流 凸凹结构由质量块 3表面设置的多个局部凸起 69构成; 再或者如图 25所示, 扰

In addition, the spoiler convex and concave structure may be various. For example, as shown in FIG. 23, the spoiler convex and concave structure is composed of a plurality of grooves 68 provided on the surface of the mass 3; or as shown in FIG. 24, the spoiler convex and concave structure Formed by a plurality of partial protrusions 69 disposed on the surface of the mass 3; or as shown in FIG. 25, The flow convex and concave structure is constituted by a plurality of partial pits 70 provided on the surface of the mass 3. Of course, in addition to the illustrated shape, the cross-sectional shape of the groove 68, the partial protrusion 69, and the partial dimple 70 can be various, and a good effect can be achieved as long as the effective contact area of the mass block and the liquid damping material can be improved.

如图 26所示本发明带有框架的调谐质量减振器, 与实施例十五的区别在于, 扰流凸凹结构由质量块 3 上设置的多个沿联接框架横截面垂向贯通的扰流孔 71 构成。 扰流孔 71浸在液体阻尼材料构成的阻尼元件 65中。 A tuned mass damper with a frame according to the present invention as shown in Fig. 26 differs from the fifteenth embodiment in that the turbulent convex-concave structure is provided by a plurality of turbulences disposed on the mass 3 in a vertical direction along the cross section of the coupling frame. The hole 71 is formed. The spoiler hole 71 is immersed in a damping member 65 composed of a liquid damping material.
质量块 3上设置的扰流孔 71可以有效提高质量块与液体阻尼材料的有效接 触面积。 当质量块 3移动时,扰流孔 71中的液体阻尼材料与质量块 3会发生相对 移动, 因此会产生阻力进行耗能,所以在质量块 3上设置扰流孔 71以后可以有效 提高产品的减振性能。由于扰流孔 71沿联接框架 2横截面垂向设置, 当质量块沿 联接框架垂向移动时, 减振效果最明显, 因此该技术方案更适合控制沿联接框架 垂向的振动。基于这种原理, 如图 27中所示, 也可以在质量块上设置沿联接框架 横截面水平向的扰流孔 72, 以控制沿联接框架横截面水平向的振动。 当然, 可以 同时在质量块上设置沿联接框架横截面垂向的扰流孔及沿联接框架横截面水平向 的扰流孔, 有利于全面提高控制水平向及垂向振动的能力, 也在本发明要求的保 护范围之中。 The spoiler 71 provided on the mass 3 can effectively increase the effective contact area of the mass and the liquid damping material. When the mass 3 moves, the liquid damping material in the spoiler 71 and the mass 3 will move relative to each other, so that resistance is generated to consume energy, so that the spoiler 71 is provided on the mass 3 to effectively improve the product. Vibration damping performance. Since the spoiler hole 71 is vertically disposed along the cross section of the coupling frame 2, the damping effect is most pronounced when the mass moves vertically along the coupling frame, so the technical solution is more suitable for controlling the vibration in the vertical direction of the coupling frame. Based on this principle, as shown in Fig. 27, a spoiler hole 72 horizontally along the cross section of the coupling frame may also be provided on the mass to control the vibration in the horizontal direction along the cross section of the coupling frame. Of course, it is possible to simultaneously provide a spoiler hole perpendicular to the cross section of the joint frame and a spoiler hole horizontally along the cross section of the joint frame, which is advantageous for comprehensively improving the ability to control horizontal and vertical vibrations. Within the scope of protection required by the invention.

Material 65.
与实施例十六中记录的技术原理相似, 由于质量块和吸振腔的腔壁上分别设 置了相互配合的动叶片和静叶片, 可以显著提高质量块与液体阻尼材料之间的有 效接触面积, 同时动叶片和静叶片在工作过程中相互配合, 还对液体阻尼材料产 生挤出的效应, 因此耗能更快, 减振效果更好。 Similar to the technical principle recorded in the sixteenth embodiment, since the moving block and the stationary vane are respectively disposed on the cavity wall of the mass block and the absorbing chamber, the effective contact area between the mass block and the liquid damping material can be significantly improved. At the same time, the moving blade and the stationary blade cooperate with each other during the working process, and also produce an extrusion effect on the liquid damping material, so that the energy consumption is faster and the vibration damping effect is better.

(5) The length dimension is easy to correct, for design Changes and construction errors are easy to adjust and correct, and the versatility of the product is better. (6) It should be noted that if the elastic element provided between the mass block and the coupling frame is pre-compressed during the assembly process of the framed tuned mass damper of the present invention, the following advantages can be obtained: Even if the material constituting the elastic member is cracked, there is internal crack, the stiffness of the elastic member and the operating frequency of the tuned mass damper do not change; on the other hand, when used to control high-frequency vibration, the amplitude of the mass is small, After pre-compression, the stiffness of the elastic component always changes linearly, which makes it easier to accurately design and control.
