利用试验和仿真相结合的方法，对某车型前通风盘式制动器进行研究。基于多功能制动器动力学试验台架，分别对两套同型号制动器试件进行制动尖叫试验，基于有限元建立制动器热机耦合分析模型，在拖滞制动模式下进行仿真计算。分析研究表明，拖滞制动模式是一个明显的热机耦合过程，其热机耦合效应与减速制动模式具有很多共同点。热机耦合效应对制动尖叫影响较大，考虑热机耦合效应有利于提高尖叫预测精度，并能够反映制动尖叫的时变特性。

Braking squeal of ventilation disc brake systems was studied through experimental and numerical analysis. Using multi-function brake dynamometer test rig, brake squeal tests of two disc brake systems were carried out. The finite element model of the disc brake was built, and the thermo-mechanical coupling effect was investigated under drag braking conditions. The simulation results show that the thermo-mechanical coupling effect exists obviously in drag braking mode, which is similar to that in emergency braking mode. This effect has a serious influence on braking squeal. It must be considered in the brake squeal simulation analysis to improve the prediction accuracy and to reflect the time-varying characteristics of the braking squeal.
