摘要

摘要: 为了研究闸片结构对盘形制动器的温度场影响，用ANSYS软件针对国内高铁的夹钳式制动器进行了整体建模和温度场有限元模拟。提出了摩擦块有无散热孔和有无垫片这四种闸片结构，用热源法和瞬态传热分析了这四种闸片在300 km/h速度下制动器的温度场，并根据温度场计算了制动器各个部件的热应力，重点对比了钢背和燕尾以及铸铁闸片托部件的温度场和热应力。模拟结果说明，高速制动时钢背的热应力超过了钢材的抗拉强度，会产生热疲劳，应当改进结构来降低。

Abstract: To reveal temperature field of disc brake caliper unit and influence of geometric structures of brake pad, a full model for high-speed train disc brake caliper unit is established and finite element analysis of transient temperature field is carried out. By applying heat flux on friction surfaces in ANSYS simulation, four designation of brake pad structures (pad with or without hole and washer) were simulated at the same setup conditions; followed by throughout comparison and discussion for the temperature field results, thermal stress of some caliper components been reviewed in details. Analysis of thermal stress indicated that the pad plate was vulnerable to thermal fatigue and the pad holder was at the margin of thermal fatigue.
