Abstract: Taking the buzzing noise of an electric SUV when it starts again after braking at low speed as an example,this paper discusses the application of NVH analysis method and BSR analysis method in solving the problem of abnormal noise. The BSR analysis method is used to quickly locate the performance attenuation problem of the rectangular seal ring. The problem of low-speed braking noise is solved by changing the structure of the seal ring and seal groove.
Key words: brake caliper, return amount, seal ring, groove, abnormal noise
