摘　　要：以履带车辆传动系统中的双排行星齿轮机构为研究对象,综合考虑行星齿轮中各齿轮副的时变啮合刚度、齿侧间隙及综合啮合误差等非线性因素,建立双排行星齿轮传动系的非线性动力学模型。根据履带车辆双排行星齿轮机构的工作原理,文中模型在第一行星排行星架固定和第二行星排内齿圈固定两种工况下分别将原系统简化为单排行星齿轮系统和单排行星轮系来处理,推导了两种工况下系统的运动微分方程,并对方程进行了量纲一化以方便后续的数值计算,最后对系统在某组参数下的动载、均载特性进行了仿真研究。By taking the double row planetary gear set in the transmission system of crawler as research subject, and by taking the The nonlinear factors as time-varying mesh stiffness, backlash and meshing error with various gear pairs in planetary gears into consideration, a nonlinear dynamic model of a two-row planetary gear set is established. Based on the operating principle of two row planetary gear set of crawler, the paper simplifies the original system into single row star train and single row planetary train so as to deduce the motion differential equation under the conditions that the first row planetary cartier is fixed and the inner rim of second planetary row is fixed, and the dimensionless of the equation is carried out to ease the subsequent value calculation. Finally, the simulation and study the load sharing behavior is carried out.
