| 摘 要： | 对原前副车架结构和材料进行优化设计,可以达到轻量化的效果。将前副车架的钢材替换为铝合金材料ZL114A,并利用CATIA三维建模软件对前副车架结构进行优化设计。经优化,前副车架质量由17 kg减少至11.76 kg,减重比例达30.8%,满足设计要求。使用Nastran软件对优化后的前副车架进行有限元分析,结果表明新结构满足各种汽车行驶工况下的强度、模态以及刚度性能要求,因此该轻量化设计方案可行,在不影响前副车架正常使用的情况下减轻质量。

| Abstract: | By optimizing the structure and materials of the original front subframe,the lightweight effect can be achieved.Aluminum alloy ZL114A was used to replace steel to reduce the weight,and then the CATIA software was used to optimize the structure of the front subframe.After optimization,the weight of front subframe is reduced from 17 kg to 11.76 kg,the weight reduction ratio achieves 30.8%,which satisfies the design requirement.Nastran software was used to analyze the new structure of frond frame.The results demonstrate that the new structure can meet the requirements of strength,mode and stiffness under various driving conditions.Therefore,the lightweight design is feasible,and it reduces the weight of the front subframe without affecting its performance. |
