摘要
假设制动盘内、外盘面具有相同的2阶正弦函数特征的初始端面跳动,针对内外侧壁厚不等的通风盘式制动器,利用Msc-marc软件建立了瞬态热-机耦合动力学仿真模型.以制动盘盘面温度场、法向应力、翘曲及厚度变化的分布特性为评价指标,在紧急制动工况下,分析了初始端面跳动对制动器热-机耦合特性的影响.研究发现,初始端面跳动的方向和大小对制动器热-机耦合特性具有显著影响.
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 Mscmarc 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 thermomechanical coupling characteristics.
