브레이크 패드 편마모 발생 및 증가 현상에 대한 해석적 고찰 = An Analytical Study on the Generation and Increase of Uneven Wear in Brake Pads

다국어 초록 (Multilingual Abstract)

This paper focuses on an analytical approach to understand the generation visually, and increase the mechanisms of uneven brake pad wear that cause disc thickness variation(DTV) and runout. In this study, nonlinear properties, such as flexibility of parts, the friction characteristics of the guide pin, the position of the caliper piston, and the stiffness of the wheel hub bearing, are defined as the ‘instability factors’ that cause uneven wear. Through the multi-body dynamics analysis that considers these ‘instability factors,’ we were able to confirm their significant impact on the generation visually and the increase in DTV and runout. The approach presented in this study is expected to make an important contribution in understanding the causes of uneven brake pad wear and in examining reduction strategies.
