摘　　要：传统的摩托车减震器端与车架连接端结构部件由于设计生产方式的限制,效能无法做到最优,文中的轻量化研究则是将拓扑优化与3D打印相结合,既能获得最佳的质量分布,又能保障部件最优的性能。该研究针对某摩托车减震器端与车架连接端结构部件,通过UG对部件进行参数化建模,利用有限元对部件进行分析,通过Altair Inspire拓扑优化的方法进行再设计,以部件主体部分为设计空间,在减轻质量的同时满足实际使用需要,最后对优化后的结构部件进行强度校核,对全部载荷工况进行分析,将优化前后的结果进行对比分析。结果表明:部件在进行优化之后质量下降了60%,并且强度不超过材料的屈服应力,最大米塞斯等效应力及最小安全系数均可满足实际需求。Due to the limitation of the design and production method,the traditional structural components of the shock absorber end and the frame connection end of the motorcycle cannot achieve the best performance.However,this lightweight research combines topology optimization and 3D printing to achieve the best mass distribution,and can guarantee the optimal performance of the components.This research is aimed at the structural components of the shock absorber end and the frame connection end of a motorcycle.The components are modeled by UG,the components are analyzed by finite element,and the Altair Inspire topology optimization method is used to redesign the components.Taking the main part of the component as the design space,it can meet the needs of actual use while reducing weight.Finally,the strength of the optimized structural component is checked,all load conditions are analyzed and the results are analyzed,and the results before and after optimization are finally compared and analyzed..The results show that the quality of the component is reduced by 60%after optimization,and the strength does not exceed the yield stress of the material.The maximum Mises equivalent stress and the minimum safety factor can meet actual needs.
