[0002] As a key component of the vehicle suspension system, the strength of the shock absorber arm directly affects driving safety and service life. Therefore, during the production process, the shock absorber arm needs to undergo rigorous strength testing to ensure that it can withstand 1.5-2 times the design limit load without breaking or plastic deformation.

[0003] Currently, existing automotive shock absorber arm strength testing devices have the following drawbacks:

[0004] 1. Lack of protective structure: If the boom breaks or fragments fly due to overload during the test, it can easily cause injury to the operator, posing a significant safety hazard.

This operation is cumbersome and inefficient, and it is impossible to quickly and accurately locate the pressure position, which affects the accuracy and convenience of the test.

[0006] Therefore, we propose a test device for the strength of automotive shock absorber arm segments. Utility Model Content
