Nonlinear Dynamic Analysis of Planetary Gear Train Systemwith Meshing Beyond Pitch Point
分析了节点外啮合行星齿轮传动系统的非线性动力学特性.优化设计了节点外啮合行星轮系各轮齿参数,采用集中质量法建立了动力学模型;采用能量法求得时变啮合刚度,考虑了齿侧间隙、支承间隙、时变啮合刚度、时变支承刚度、时变摩擦因数的影响;基于Hertz接触理论求得滚动轴承时变支承刚度;计算了齿间载荷分配规律,基于弹流润滑(Elastohydrodynamic lubrication,EHL)理论计算了齿面时变摩擦因数;采用数值积分法对系统非线性动力学方程进行…查看全部>>
Nonlinear dynamic analysis was performed on a planetary gear transmission system with meshing beyond the pitch point. The parameters of the planetary gear system were optimized,and a two-dimensional nonlinear dynamic model was established using the lumped-mass method. Time-varying meshing stiffness was calculated by the energy method. The model consumes the backlash,bearing clearance,time-varying meshing stiffness,time-varying bearing stiffness,and time-vary…查看全部>>
