Meanwhile, the support system further comprises a plurality of auxiliary gas bags, wherein the upper part of each auxiliary gas bag is fixedly connected with the movable coil, the lower part thereof is fixedly connected with thecentral magnetic pole, and the auxiliary gas bags are connected with a gas supply system. The movable coil support system with large load structure has simple structure and convenient installation and maintenance, doesn't affect the performance of the vibration test equipment, and is applied to the test of a heavy-duty test sample. The movable coil support system with the large-load structure iswidely applied to the technical field of vibration test.
Description
Technical field
The utility model relates to a kind of vibration rig in the vibration test technical field, is specifically related to a kind of moving-coil support system with heavy load structure.
Background technology
At present, in vibration rig, usually adopt moving-coil support system as shown in Figure 1, it mainly comprises a central balloon 5, this central balloon 5 is connected with the axis of guide 4, and guide bearing 3 is fixed on the central magnetic pole 2, and the axis of guide 4 passes guide bearing 3 and is connected with moving-coil 1, but the little defective of this kind moving-coil supporting system ubiquity moving-coil anchorage force can't adapt to the needs that heavy test specimen is tested.For overcoming above-mentioned defective, usually adopt the method that increases expansion table top and supplemental support to improve the load-bearing capacity of moving-coil support system at present, but this mode can increase the equivalent mass of moving-coil greatly, has a strong impact on the usability of vibratory equipment, and has also strengthened the manufacturing cost of testing equipment.Another kind of mode comparatively commonly used is that whole shaking table stage body periphery is sealed fully, even moving-coil is in the inner closed cavity that forms of vibration stage body, to improve the moving coil bearing ability, but it is comparatively complicated to the operation of shaking table stage body integral sealing, there is carelessness promptly easily to cause gas leakage slightly, and closed cavity internal gas pressure and central balloon differ bigger, can't constitute air-channel system in parallel, and then still can't promote the load-bearing capacity of moving-coil support system significantly.
The utility model content
The purpose of this utility model is to propose a kind of simple in structure, convenient for installation and maintenance, can adapt to the needs that heavy test specimen is tested, and the moving-coil support system with heavy load structure that can impact the vibration rig performance not is to overcome deficiency of the prior art.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of moving-coil support system with heavy load structure, comprise central balloon, the axis of guide and guide bearing, central balloon is connected with the axis of guide, guide bearing is fixed on the central magnetic pole, and the axis of guide passes guide bearing and is connected with moving-coil, it is characterized in that, described support system also comprises a plurality of auxiliary balloon, fixedlying connected with moving-coil in its top, fixedlys connected with central magnetic pole in the bottom, and these a plurality of auxiliary balloon are connected with air supply system.
Concretely, fixedly connected with central magnetic pole by the air bag holder in described auxiliary balloon bottom.
Described auxiliary balloon bottom is provided with air intake opening, and this air intake opening is connected with air supply system by a tracheae.
Described tracheae is tightly connected by the fast plug in gas-tpe fitting and the auxiliary balloon air intake opening that can carry out 360 ° of rotations.
Be interconnected by tracheae between described each auxiliary balloon, and with the parallel air supply system that is connected of central balloon.
Described auxiliary balloon is eight, and it is symmetrically distributed between moving-coil and the central magnetic pole.
This has in the moving-coil support system of heavy load structure, employing increases the mode that a plurality of auxiliary balloon that are interconnected are set between moving-coil and central magnetic pole, effectively improved the load of moving-coil, compare with variety of way of the prior art, both do not increased the equivalent mass of moving-coil, also need not shaking table stage body structure is carried out bigger transformation, convenient for installation and maintenance, and auxiliary balloon and central balloon all can keep good impermeability, carrying air bag again and respectively is interconnected, and with the parallel air supply system that is connected of central balloon, can make each air bag load-bearing capacity basic identical like this, thereby further make on the moving-coil each position in process of the test stressed evenly, guarantee that shaking table has stable experimental performance.
Have the assembling difficulty of the moving-coil support system of heavy load structure for further reducing this, improve assembling speed, the mode of optimizing is to adopt a fast gas-tpe fitting of inserting that can carry out 360 ° of rotations that tracheae and auxiliary balloon air intake opening are tightly connected.This push-in gas-tpe fitting can be the existing market common type.
This assembling process with moving-coil support system of heavy load structure is: at first each air bag holder is installed on the central magnetic pole, the fast plug in gas-tpe fitting and the auxiliary balloon air intake opening that can carry out 360 ° of rotations thereafter are tightly connected, then auxiliary balloon is threaded with the air bag holder, after treating each auxiliary balloon all fixed installation being finished, fixedlyed connected with moving-coil in each auxiliary balloon top again and get final product.
Compared with prior art, the beneficial effects of the utility model are: this moving-coil support system with heavy load structure is simple in structure, convenient for installation and maintenance, can not impact the vibration rig performance, can adapt to the needs that heavy test specimen is tested.The utility model can be widely used in the vibration test technical field.
