摘　　要：采用动力学有限元软件ANSYS/LS-DYNA对齿轮动态接触问题进行分析,结合LS-PREPOST后处理器得到了齿轮在不同时刻齿面的啮合接触应力、有效应力、压力曲线等变化情况,并在此基础上对齿轮副安装轴向误差引起的典型故障进行模拟,分析结果充分体现了该方法在齿轮系统动态分析和故障模拟方面的优越性,并为探寻齿轮系统故障机理提供了手段。By ANSYS/LS-DYNA, the dynamic contact of gears is analyzed. With the tool box of LS-PREPOST, the changing circumstances at different time,such as the contact stress, effective stress, pressing curve have been achieved. The model fault brought by the axial error when the gears are installed is simulated. The analyzing result indicated that the advantage of the method on the side of dynamic analysis and fault simulation of the gears system and it provides a new means to explore the failure mechanism of gears.
