摘　　要：为研究某型号双挂厢式列车中置轴挂车的结构性能,利用三维建模软件搭建中置轴挂车的整体模型,进行适当的零件删减与结构简化后,导入到有限元分析软件对其进行两种工况的结构静力学分析,得出相应的等效应力云图。基于应力云图,对应力集中部分进行结构优化。优化结果表明该中置轴挂车结构的安全性与可靠性得到提高。To study the structural performance of the centre-axle trailer of a double-trailer combination vehicle,an overall model of the centre-axle trailer is constructed by using the three-dimensional modelling software,and after appropriate part deletion and structural simplification,it is imported into the finite element analysis software for structural static analysis under two working conditions to obtain the corresponding equivalent stress nephogram.Based on the stress nephogram,the structure of the stress concentration part is optimized.The optimization results show that the safety and reliability of the centre-axle trailer structure are improved.
