| 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.

| Abstract: | Supposed disc inner and outer surfaces have the same initial 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 on emergency braking condition. The research results show that initial SRO, its direction and size have significant effects on brake thermo-mechanical coupling characteristics. |

| Keywords: | disc brake initial SRO thermo-mechanical coupling transient temperature thermo-elastic deformation |
