Description

technical field [0001] The invention belongs to the field of auto parts testing, in particular to a torsion durability test device for a stabilizer bar bushing. Background technique [0002] The application of bushings can be seen everywhere in the automotive field. The main reason is that people have higher and higher requirements for energy saving, environmental protection, comfort, reliability, etc. in the suspension system, such as the hinge connecting the stabilizer bar and the sub-frame. The rubber bushing connection method is adopted, the rubber bushing has good vibration isolation performance, has the advantages of elastic characteristics and attenuation characteristics, and has become an indispensable and important component of the car. With the characteristics of anisotropy, different rigidity values ​​can be selected in the axial, radial and torsional directions. It can be vulcanized together with the metal structure, which simplifies the structure of fixing and s...

AI Technical Summary

Problems solved by technology

Therefore, the main force of the stabilizer bushing is the axial rotation. Due to the superelastic structure of the bushing, it is also a difficult point in CAE simulation. Therefore, the main method to investigate the durability of the bushing is the durability test. Test is a direction worthy of research, especially in the initial stage of bushing development, without a stabilizer bar structure, it is impossible to do system tests together, and it is necessary to use a simple and high-precision device to complete the durability test, and the current test device in this direction is relatively In summary, it is of great significance to develop a stabilizer bar torsional durability test device
