摘　　要：建立了某型汽车盘式制动器三维模型,分析了其制动盘-衬块摩擦副间的接触关系,并对制动过程中摩擦副的温度场进行了仿真。同时使用LM算法进行多元非线性回归分析,分别计算了不同的摩擦因数、制动压力、初始转速和时刻下制动盘的最高温度。有限元仿真与回归分析的结果基本吻合,验证了所建温度模型的正确性。本研究可为汽车盘式制动器设计中的温度预测提供参考。A 3D model for the disc brake of a vehicle is established, the contact relationship of disc-pad friction pair is analyzed, and the temperature field of friction pair in braking process is simulated. Meanwhile a re- gression analysis is also conducted with LM algorithm. The peak temperatures of brake disc at different friction coef- ficients, braking pressures, initial rotational speeds and times are calculated in both FE simulation and regression a- nalysis, with their results well agreeing with each other, verifying the correctness of temperature model built. The study provides references for temperature prediction in designing vehicle disc brake.
