摘　　要：文章针对某车型前盘式制动器开发制动热抖动实际案例,利用制动盘相关铸造工艺和热处理方法对铸造内应力进行优化,降低制动盘热变形,改善常规用户对高速制动工况热抖动的抱怨。在验证优化方案有效性上采用台架制动热变形试验、台架制动力矩试验以及整车路试等方法进行方案验证。试验验证分析表明,制动内应力优化对改善制动热抖动具有显著作用。For the actual case of the brake hot judder for the front disc brake in a vehicle development,by optimizing the internal stress of the casting and thermal treatment method of brake discs,the thermal deformation of the brake disc is reduced,and the hot judder complaint of the normal drivers in the braking conditions with high speed driving is improved.In terms of the verification for the optimization effectiveness,the thermal deformation test,the brake torque variation test and the vehicle road test are used to verify the scheme.Test verification analysis shows that the internal stress optimization of brake disc has a significant effect on improving brake hot judder.
