摘　　要：在考虑齿轮时变啮合刚度、齿面间的摩擦力和齿侧间隙等非线性因素情况下,利用散体单元法建立齿轮耦合系统的非线性动力学DEM模型,给出计算方程和计算过程,为以后对整个复杂的多平行轴系统进行非线性动力学特性研究做好准备。Considering non-linear factors, such as time-varying mesh stiffness, friction effect between tooth pairs and backlash clearance, etc., according to DEM, we set up the nonlinear dynamics DEM model of gears coupling system, gave calculation equation and calculation process, This will help the next study of nonlinear dynamics characteristics of a whole complicated parallel axises rotor system.
