基于solidThinking Inspire的控制臂优化设计

Optimization design of control arm based on solidThinking Inspire

传统的产品设计往往需要通过设计—验证—改进等步骤,由于验证的时间较长,往往会导致整个设计周期增加。文章利用Altair公司的优化软件solidThinking Inspire建立了汽车控制臂优化模型,并使用底盘强度分析中较为常用的工况进行校核。根据设定的不同目标,得到了相应的拓扑优化结果。进而针对原始模型进行几何重构。新的结构不但能满足强度要求,而且重量也有一定的减轻,优化效果明显,缩短了设计周期,提高了产品设计工程师的工作效率。

Traditional product design often requires steps through design-verification-improvement,often due to longer verification times,resulting in an increase in the overall design cycle.In this paper,Altair's optimization software solid Thinking Inspire is used to establish the vehicle control arm optimization model,and it is checked by the more common working conditions in chassis strength analysis.According to the different goals set,the corresponding topology optimization results are obtained.Then geometric reconstruction is performed for the original model.The new structure not only meets the strength requirements,but also has a certain weight reduction,the optimization effect is obvious,the design cycle is shortened,and the work efficiency of the product design engineer is improved.
