Description

Technical Field

[0001] This utility model relates to the field of vehicle assembly noise verification technology, and in particular to a tooling for quickly simulating real vehicle assembly noise verification. Background Technology

[0002] The secondary vulcanization process for stabilizer bar bushings is increasingly widely used in stabilizer bar manufacturing. This process fundamentally avoids stabilizer bar noise issues that occur during vehicle operation. Stabilizer bar noise in vehicles is mainly caused by two factors: firstly, poor vulcanization (poor adhesion) between the bushing and stabilizer bar leads to friction noise; secondly, insufficient interference fit between the bushing and clamp causes relative rotation and friction noise. These two issues are the two main reasons for noise problems in the market after the widespread adoption of the secondary vulcanization process for stabilizer bar bushings. Online monitoring of the vulcanization effect completely eliminates noise caused by poor vulcanization (poor adhesion) of the stabilizer bar and bushing. A method for quickly identifying friction noise between the stabilizer bar bushing and clamp is needed to prevent products with friction noise from entering the market and causing complaints from end-users.

[0003] Existing devices mostly perform manual verification of abnormal noise by assembling the stabilizer bar onto a tooling or subframe during testing. This process is time-consuming and inefficient. Therefore, a tooling for rapid simulation of real vehicle assembly and abnormal noise verification is proposed. Utility Model Content
