Problems solved by technology
At present, the design and development technology of the intermediate support in foreign countries is relatively mature, but there is a big gap in China. At present, there is no good device to test the stiffness of the intermediate support ring. Even if there is an elastomer performance test bench, there is no corresponding test device. , it is difficult to analyze the vibration isolation performance of the intermediate support. In order to master the design and development technology of the intermediate support ring, the characteristics of the intermediate support ring in the real vehicle structure are tested, and the working mechanism of the intermediate support ring is analyzed in combination with the theory of vehicle dynamics. , so there is an urgent need for an efficient and reliable test device for the stiffness of the intermediate support ring

The invention provides a test device for testing rigidity of an intermediate supporting ring. A supporting ring sample is installed in the test device to perform X-direction, Y-direction and Z-direction testing. The test device is mainly composed of an actuator, a fixing part, a supporting part and a connecting part. One end of the fixing part is connected with the supporting ring sample through threads, and the other end of the fixing part is rotatably connected on the supporting part. The connecting part is connected with the fixing part and the actuator head through the threads.
Description
technical field [0001] The invention relates to a test device, in particular to a test device for testing the stiffness of an intermediate support ring, which belongs to the technical field of vehicle safety design. Background technique [0002] The middle support ring plays an important role in the automobile suspension system, and has a good function of vibration and noise reduction. The mechanical characteristics of the middle support ring affect the elastic movement and handling stability of the automobile suspension system. The middle support ring improves the smoothness of the car. Sex and comfort play an important role. At present, the design and development technology of the intermediate support in foreign countries is relatively mature, but there is a big gap in China. At present, there is no good device to test the stiffness of the intermediate support ring. Even if there is an elastomer performance test bench, there is no corresponding test device. , it is diffic...
