重型轨道车动力总成吊挂静力学分析及拓扑优化

Static Analysis and Topological Optimization of Heavy Rail Motor Car Powertrain Hanging

以某重型轨道车动力总成吊挂为研究对象,利用ANSYS对其进行仿真优化设计,并将优化后的方案与原方案进行强度与模态的对比,确定拓扑方案的可行性。优化后的吊挂设计降低了吊挂自身重量,提高了材料利用率,降低了材料成本。

This paper takes the powertrain hanging of heavy rail motor car as the research object,uses ANSYS to carry out simulation and optimization design,and compares the strength and mode of the optimized scheme with the original scheme to determine the feasibility of the topology scheme.The optimized hanging design reduces the weight of the hanging itself,improves the utilization rate of materials,and reduces the cost of materials.
