摘要

基于某型商用车前桥,提出了一种基于二次优化思想的轻量化设计方法。建立了该前桥有限元模型并进行仿真分析,结合疲劳耐久试验探究前桥真实载荷情况,验证了有限元模型的准确性。对前桥真实材料进行静载拉伸、弯曲疲劳试验,获得热处理后前桥材料的力学性能指标作为轻量化参考。前桥整体模型进行拓扑优化后基于力学模型进行二次优化,保证前桥结构满足强度、刚度和服役寿命的前提下,实现轻量化设计。最终总质量减少5.7 kg,达到轻量化设计目标。

Abstract

A lightweight design method based on the idea of secondary optimization was proposed for a certain commercial vehicle front axle.The finite element model of the front axle was established and simulated.Combined with the fatigue endurance test,the true load of the front axle was investigated to verify the accuracy of the finite element model.The static tensile load and bending fatigue test of the real material of the front axle are taken as the light weight reference for obtaining the mechanical performance index of the front axle material after heat treatment.The overall model of the front axle is optimized and secondary optimization based on the mechanical model to ensure that the structure of the front axle meets the requirements of strength,stiffness and service life while achieving a lightweight design.The final total mass reduced 5.7 kg,to achieve the purpose of lightweight design.
