| 目的 增强高速列车的制动性能，并延长制动盘的使用寿命。方法 针对制动盘多次制动作用下的热-力耦合规律进行研究，采用微元法思想计算摩擦表面的热流密度，并考虑多次制动工况建立制动盘有限元仿真模型，分析不同制动工况下制动盘翘曲变形量的变化规律。建立制动盘整形过程的有限元模型，分析制动盘翘曲变形量与整形力之间的关系。结果 整形后的制动盘翘曲度值均低于0.2 mm，塑性应变不高于0.001。结论 通过建立的矫正力与翘曲度之间的关联曲线，能够为制动盘的整形修复提供有力的理论支持。 |

| The work aims to increase the braking performance of high-speed trains and prolong the service life of brake discs. The thermal-mechanical coupling laws of the brake disc under multiple braking were studied and the idea of micro-element method was used to calculate the friction surface of the heat flow density. The multiple braking conditions were considered to establish a finite element simulation model of the brake disc and the warping deformation of the brake disc under different braking conditions was analyzed. The finite element model of brake disc shaping process was established to analyze the relationship between brake disc warping deformation and shaping force. The warpage value of the brake disc after shaping was lower than 0.2 mm, and the plastic strain was not higher than 0.001. The correlation curve between the corrective force and the warpage is established to provide strong theoretical support for the shaping and repair of the brake disc. |
