摘要
应用ANSYS Workbench软件建立了纯电动车的盘式制动器的有限元模型,对模型进行了力学分析。在满足盘式制动器的自身刚度、强度要求同时,运用拓扑优化技术对钳体和支架进行了结构优化,研究如何进行有效减重。在材料方面,用ZL101为基体SiC增强的铝基复合材料代替HT250材料对制动盘进行了优化。盘式制动器在优化后,制动钳减轻了71%,支架减轻了70.7%,制动盘减轻了63%,减重效果良好,部件的性能指标也都满足要求。
This study uses ANSYS Workbench software to establish a finite element model of the disc brake of a pure electric vehicle,and analyzes the model mechanically.While meeting the rigidity and strength requirements of the disc brake,topology optimization technology is used to optimize the structure of the caliper body and the bracket,and how to effectively reduce weight was studied.In terms of materials,the brake disc is optimized with ZL101 as the matrix SiC-reinforced aluminum-based composite material instead of HT250.After optimization of the disc brake,the brake caliper is reduced by 71%,the bracket is reduced by 70.7%,and the brake disc is reduced by 63%.The weight reduction effect is very obvious.At the same time,it can be seen from the results of mechanical analysis that the performance indicators all meet the performance requirements of pure electric vehicle disc brakes.
