| 摘 要： | 由于热量集中于制动盘的表面造成热弹不稳定性(TEI)而引起热变形.这样可能发生大家知道的低频强烈振动.因为在盘和衬块的接触面间的摩擦系数变化,在摩擦衬决发生尖叫声.通过对热聚集和尖叫现象的联合分析,对高热和机械特性可设计一最佳的盘和摩擦衬块.本文同时考虑了热和机械不稳定性按照盘的厚度,卡钳的加压方式,衬片弧长进行了数值...

| Abstract: | The thermal distortion induced by thermoelastic instability(TEI) results in hot spots on the surface of the brake disc.This can incur low-frequency vibration known as judder.In pad-induced squeal noise,mode coupling occurs owing to the variation in the friction coefficient between the disc and pad,inducing highfrequency noise.Through a coupled analysis of hot spots and squeal phenomena,an optimum disc and pad design can be designed for higher thermal and mechanical performance.In this study,numerical and ex... |
