摘要

摘要: 研究了铁路机车车辆运行过程中车轮辐板机械应力场的两种数值计算方法，将机械力进行傅立叶级数展开构建二维模型，通过对比二维轴对称模型和三维实体模型的计算结果，验证了二维轴对称模型的可行性。分析了车轮在运行过程中三种典型工况下辐板中机械应力场的分布情况及变化规律，通过对比车轮辐板的Von-Mises等效应力和径向应力，发现轮毂内圆角区域最为薄弱，承受较大的交变载荷。

Abstract: 3-Dimensional solid model and 2-Dimensional axisymmetric model, as well as two numerical simulation methods of calculating mechanical stress field, were introduced in this paper. The 2-Dimensional axisymmetric model was established with the Fourier expansion of mechanical force. Results of these two methods verified that.The stress distribution of wheel web plate under three typical conditions had been analyzed, and von-misses equivalent stress and radial stress variation during one cycle of wheel under three conditions had been obtained. The results of stress analysis show that: wheel hub fillets are weak areas.
