摘要
传统城轨车辆转向架多采用钢质结构,虽然承载可靠,但是质量偏大,导致能耗较高且难以兼顾运行经济性与动力学性能。因此,如何实现轻量化与性能平衡成为当前研究的重点。鉴于此,提出基于拓扑优化的6061-T6铝合金转向架轻量化设计方法。通过优化区域划分、参数设定和结构重构,并结合静力学、动力学及经济性验证,最终实现转向架减重,且关键性能优于原结构,为实现城轨转向架轻量化提供了可行路径。
Traditional urban rail vehicles often use steel structures for their bogies,which are reliable in load-bearing capacity but heavy,resulting in high energy consumption and difficulty in balancing operational economy and dynamic performance.Therefore,how to achieve a balance between lightweight and performance has become a current research focus.In view of this,a lightweight design method for 6061-T6 aluminum alloy bogies based on topology optimization is proposed.By optimizing regional division,parameter setting,and structural reconstruction,combined with statics,dynamics,and economic verification,the weight reduction of the bogie is ultimately achieved,and the key performance is better than the original structure,providing a feasible path for achieving lightweighting of urban rail bogies.
