初始端面跳动对制动器热-机耦合特性的影响
Impacts of Initial SRO on Thermo-mechanical Coupling Characteristics of Disc Brake
摘要
Abstract
Supposed disc inner and outer surfaces have the same initial surface run-out (SRO) with 2 order sine function characteristics, the transient thermo-mechanical coupling dynamic model of ventilated disc brake with asymmetrical outer and inner thickness was established by means of Msc-marc software. With distribution characteristics of disc temperature field, normal stress field, thermal coning and thickness variation for the evaluation, the impacts of initial SRO on brake thermo-mechanical coupling characteristics were analyzed under emergency braking condition. The simulation results show that initial SRO, both its direction and amplitude, have significant effects on brake thermo-mechanical coupling characteristics.关键词
