Abstract: Due to the importance of the brake lines in FSEC competitions, it is necessary to perform a thermal analysis simulation design of the brake disc styles in Ansys while considering the thermal decline of the disc brakes.After obtaining the minimum compression force of the brake disc friction sheet by preset the parameters of the car, Catia, Ansys Workbench are used to compare the heat dissipation performance of the brake disc in different punching schemes and determine the brake disc processing scheme that produces the minimum heat, so as to provide reference for the brake disc design.

摘要： 由于中国大学生电动方程式汽车大赛（FSEC）中制动系的重要性，有必要在考虑盘式 制动器热衰退的前提下在 Ansys 中对各样式的制动盘进行热分析。文章通过预设赛车各项参 数求得制动盘摩擦片最小压紧力后，利用 Catia 建立三维模型，使用 Ansys Workbench 对制动 盘进行热分析，比较不同打孔方案制动盘的散热性能，确定产生最小热量的制动盘加工方案， 为制动盘设计提供参考。
