摘　　要：结合某新型商务车副车架的开发要求,在副车架初步设计阶段,利用ABAQUS软件对其常用的十个工况进行强度分析。根据各工况的应力分布情况,找出了应力集中的位置并分析其产生的原因,通过Optistruct优化工具对五个应力较大工况进行优化设计,根据优化后的截面尺寸再次进行强度分析,分析结果显示副车架在满足应力的要求下,总质量减小了15.31%,指导了新车副车架的开发。通过对副车架优化前后的应力对比,表明提出的优化方案是正确的。According to the research and development requirements of a new vehicle,a business car in the initial development by the ABAQUS software.According to the analysis of ten common conditions of stress,and the location of stress concentration was found out and its causes were analyzed.An optimal design for the five higher stress conditions was done by the Optistruct tool,according to the optimized section size,the subframe of the business car was analyzed again.From the analyzed results,the total mass was reduced 15.31% in the premise request of stress.Through the two structure＇s analysis and comparison of the proposed optimization shows the optimal method is correct.
