摘　　要：运用有限元仿真软件ANSYS建立1 067 mm轨距货车转向架侧架的有限元模型;根据北美铁道协会标准AAR M-203∶2012确定侧架的结构刚度载荷工况和疲劳强度试验计算工况,并对侧架的结构刚度和疲劳强度进行计算,重点分析其疲劳强度危险点可能出现的位置。结果表明,侧架在各工况下的最大变形小于标准要求的许用值;侧架各区域在疲劳强度载荷下的累积损伤均小于1,满足标准规定的疲劳试验要求。A finite element model of side frame of the 1067 mm gauge freight car bogie is established by using the finite element simulation software ANSYS. According to the North American Railway Association Standard AAR M-203: 2012, determine the structural stiffness load conditions and fatigue strength test calculation conditions of the side frame. And calculate the structural rigidity and fatigue strength of the side frame, focusing on analyzing the possible locations of the fatigue strength danger points. The results show that the maximum deformation of the side frame under various working conditions is less than the allowable value required by the standard;the cumulative damage of each area of the side frame under fatigue strength load is less than 1, which meets the fatigue test requirements specified by the standard.
