基于ANSYS的地铁车辆逆变器吊装结构强度分析

摘要

针对列车运行时逆变器吊装结构存在着焊缝的开裂状况,依照标准EN 12663《铁道车辆车体结构要求》,以某新型地铁车辆底部的逆变器吊装结构为研究对象,根据标准中的不同工况进行有限元分析.分析结果显示,逆变器吊装结构在给定载荷工况下应力均小于材料的屈服应力,满足材料强度需求.%Aiming at the crack existence in the hoisiting structure of car inverter at highspeed operation, the bottom of the hoisting structure model is simulated in accordance with the standard EN 12663"body structure of railway vehicle requirements".Finite element analysis results show that the yield stress of the inverter hoist-ing structure under given load conditions meets the demand of material strength.
