摘要
当对制动器进行设计时,需对像循环制动工况等重负荷工作条件下的制动盘热机耦合现象进行研究。考虑到采用完全热机耦合方法存在求解时间长、且不容易收敛的缺点,不适合分析制动时间较长的重负荷制动工况,同时传统的基于固定热源的顺序热机耦合又不能很好地模拟热源转动的真实情况。因此,提出基于转动热源的顺序热机耦合法,在验证该方法的可行性后,将其运用至循环制动工况的热机耦合仿真分析中,仿真结果令人满意,具有工程价值意义。
When designing the disk brake,it is necessary to study the coupling phenomenon of the brake disk under the heavy load conditions such as repeated brraking. Since the solution time of complete thermos-mechanical coupling method was longer and it was hard to converge,which was not suitable for analyzing heavy load braking conditions with long braking time;Meanwhile the method of sequential based on fixed heat source can not achieve the rotation of friction heat source. Therefore a sequential thermo-mechanical coupling method based on rotating heat source is proposed. After verifying the feasibility of the method,it is applied to the thermos-mechanical simulation analysis of the disk in the cyclic braking condition. The simulation results are satisfactory and have the significance of engineering value.
