摘　　要：零件轻量化是机械制造领域的重要研究方向。以中国大学生方程式汽车大赛BTR-X的悬架立柱作为例,在分析其实际受力情况的基础上,利用Altair inspire form软件以最大化刚度为目标对其进行了减重设计和拓扑结构优化。得到了带刹入弯工况条件下两种不同设计方案的应力、应变值及安全系数,并对比了其优缺点。结果表明,在最佳优化方案中,BTR-X悬架立柱最大有效应力为557.4 MPa,减重18.4%,提升了车辆的操稳性,实现了其轻量化的目标,对进一步提升FSCC赛车的性能有一定的参考价值。最后,通过选择性激光烧结成功实现了优化悬架立柱结构的3D打印成型,为FSCC赛车的轻量化设计及加工提供了新思路。The practice of lightweight parts is an important research direction in the field of mechanical manufacturing.In this study,the suspension column of the Formula Student Combustion China(FSCC) BTR-X was taken as an example.Based on the analysis of its actual force,the Altair inspire form software was employed to perform weight reduction design and topology optimization with the goal of maximizing stiffness.The stress,strain values and safety factors of two different design schemes were obtained under the condition of entering the bend with brakes,and then their advantages and disadvantages were compared.In the best optimization scheme obtained,the maximum effective stress of the BTR-X suspension column was 557.4 MPa,and the weight was reduced by 18.4%,thus improving the stability of the vehicle.Accordingly,the lightweight goal was achieved,which has certain reference value for further improving the performance of FSCC racing cars.Finally,the 3D printing molding process of the optimized suspension column structure has been successfully realized by selective laser sintering(SLS),providing a new route for the lightweight design and processing of FSCC racing cars.
