The engineering structures such as buildings, bridges and the like have special configurations, or the actual compression state of part of rubber supports is far from the design state under the accumulation of the long-term peristalsis effect. In the prior art, the deviation between the actual pressure stress and the designed pressure stress of the support is difficult to find in time, and the rubber support is difficult to ensure to work safely and effectively in a service period.
After the rubber material is subjected to a vulcanization process, the internal molecular chains are mutually overlapped to form a net structure, and the internal molecular chains cause the rubber material to have higher elasticity. The inner molecular chain is in a disordered coiled state when the rubber material is not acted by external force. Under the action of external force, the molecular chains curled inside the rubber material are stretched, and the molecular chains tend to be in a regular state. The larger the external force, the straighter the chain molecules are stretched and the more regular the arrangement. Macroscopically, the greater the compressive stress to which the rubber mount is subjected, the more repulsive the probe is to the penetration. The probe penetrating into the rubber support is tightly wrapped by the rubber, and the frictional resistance borne by the probe is increased along with the increase of the compressive stress borne by the rubber support.
Based on the above principle, the embodiment of the present invention provides a device for rapidly detecting an internal force of a rubber support, please refer to fig. 1 to 4, which includes a driving mechanism 1, a detecting mechanism 2 and a power supply mechanism 3.
The driving mechanism 1 includes a driving mechanism body and a movable end, and the movable end moves linearly along the driving mechanism body. The drive mechanism 1 may be driven electrically, or may be driven pneumatically or hydraulically.
When the device is used, the driving mechanism 1 enables the movable end to move along a straight line through circuit control or mechanical control.
The detection mechanism 2 comprises a probe 21, the probe 21 is arranged on the movable end of the driving mechanism 1, and the end of the probe 21 far away from the driving mechanism body is a tip along with the linear motion of the movable end.
In use, the detection mechanism 2 is disposed on one side of the rubber mount 100. And starting the driving mechanism 1, wherein the movable end is close to the rubber support 100, the end of the probe 21 close to the rubber support is a tip, and the tip of the probe 21 penetrates into the rubber support.
It should be noted that, in the device for rapidly detecting internal force of a rubber mount provided in the embodiment of the present invention, the probe 21 penetrates into the rubber mount, and the frictional resistance of the rubber mount to the probe 21 indirectly reflects the pressure stress in the rubber mount. The process of penetrating the probe 21 into the rubber mount may cause some damage to the rubber mount, and therefore the size of the probe 21 needs to be strictly limited.
In one embodiment, the diameter of the probe 21 does not exceed 3mm, minimizing damage to the rubber mount during the testing process.
The power supply mechanism 3 is connected to the driving mechanism 1 through a lead to provide stable voltage for the driving mechanism 1, so that the driving mechanism 1 pushes the movable end to be close to the rubber support with preset power.
The principle of the detection process is as follows:
the driving mechanism 1 pushes the probe 21 to pierce the rubber support with a predetermined power P, and after a certain time t, the work W = nPt is performed on the probe 21, and n is the energy conversion efficiency of the piercing process.
According to the characteristics of the molecular chains in the rubber support, the greater the compressive stress the rubber support is subjected to, the greater the frictional resistance to the probe inserted therein.
During the process that the probe 21 penetrates into the rubber support, the work of overcoming the frictional resistance of the rubber support is Q = fx = mW = mnPt, wherein m is the energy conversion efficiency during the process of overcoming the friction, f is the frictional resistance of the rubber support to the probe, and x is the depth of the probe penetrating into the rubber support.
From the above, m and n are constants, and P, t is a predetermined value. The greater the compressive stress to which the rubber mount is subjected, the greater the frictional resistance f to the probe 21 and the shallower the depth x into which the probe penetrates. The compressive stress is positively correlated with the frictional resistance f and negatively correlated with the probe penetration depth x.
Before the target rubber support is detected, different pressures are applied to the same type of rubber supports, and a relation curve or a comparison table between the compressive stress and the penetration depth is established, please refer to fig. 4. During field detection, the pressure stress of the rubber support can be read quickly according to the depth of the probe penetrating into the rubber support.
