摘　　要：采用ANSYS有限元软件分析计算了HXD1B型大功率机车辅助变压器夹件承受垂向3g、横向3g和纵向5g的3个方向峰值加速度冲击时整体夹件的机械强度,各种工况下的最大应力都小于材料许用应力,最后通过试验验证了夹件机械强度的可靠性。With finite element analysis by the ANSYS software, the mechanic strength was analyzed and calculated when the auxiliary transformer clamping piece was brought to bear three direction impact of vertical 3g transverse 3g and longitudinal 5g peak acceleration, which indicated the max stress of all working conditions was less than material permitted. The reliability of clamp mechanic strength was verified by experiment too.
