某新能源汽车制动踏板总成轻量化设计

为了校核某新能源汽车制动踏板总成的性能,首先基于Hypermesh软件建立其有限元模型。其次分别对其进行刚度性能分析、强度分析和疲劳分析。结果表明:其最大位移量小于目标值;其最大应力小于材料屈服;其本体及其焊缝的最大损伤值均小于1,三者的分析结果均能够满足设计要求。然后采用Isight集成平台对其进行轻量化设计,得到了其最优的厚度参数,分析结果表明:优化之后其各项性能也可以符合目标要求。最后对其优化方案进行实车试验,并且通过了整车道路验证。

Lightweight Design of a New Energy Vehicle Brake Pedal Assembly

This paper is aiming at checking the performance of a new energy vehicle brake pedal assembly. Firstly, its finite element model is established by Hypermesh software, Secondly, the stiffness performance analysis, strength analysis and fatigue analysis are carried out. The results show that the maximum displacement is less than the target value, the maximum stress is less than the material yield, the maximum damage value of the body and its weld is less than 1, and the analysis results of the three can meet the design requirements. Then, the ISIGHT integrated platform is used to lightweight design, and the optimal thickness parameters are obtained. The analysis results show that the optimized performance can also meet the target requirements. In the end, the optimization schemesare tested on the real vehicle, and it passes the vehicle road verification.
