摘　　要：以渐开线齿轮为例,通过程序求得渐开线上的关键点,又在ANSYS中通过关键点创建齿轮渐开线,建立齿轮的有限元模型,导入到ADAMS中进行多体动力学仿真。通过ADAMS和ANSYS的结合,成功地实现了柔性齿轮系统动力学的仿真计算,使仿真结果更加贴合实际。实例表明,该柔性体仿真方法对包括齿轮机构在内的复杂机械系统的多体系统动力学仿真具有一定的参考意义。The paper takes involute gear as study objective, and derives the key point on the involute by means of the program, creates the gear＇s involute by means of the key point from ANSYS. builds the finite element model of the gear, carries out the multi-body dynamic simulation by means of ADAMS. It also combines the ADAMS with ANSYS to realize the dynamic simulation calculation of the flexible gear train. This method can make the simulation result closer to actual one. The simulation example shows that this flexible body simulation method has some reference for the multi-body system＇s dynamic simulation of the gear trains or more complex mechanical systems.
