摘要

为了研究RV减速器的动态特性,参考2K-H行星齿轮的建模方法,简化并建立了RV减速器的平移-扭转耦合动力学模型,采用龙格-库塔法求解系统的非线性时变方程,得到了不同部件的平移微位移和啮合微位移。采用有限差分法研究了行星载体动态特性对时变刚度、啮合误差、啮合间隙和外部激励等非线性因素的敏感性。研究发现,行星载体的平移微位移对外界激励最敏感,其次是啮合误差,对其他因素的敏感性较弱。

Nonlinear Characteristics Analysis of Translational-Torsional Coupled Dynamic Model of RV Reducer
In order to study the dynamic characteristics of RV reducer, a translational-torsional coupled dynamic model of RV reducer is simplified and established with reference to the modeling method of 2K-H planetary gear, Runge-Kutta method is used to solve the nonlinear time-varying equations of the system, and translational micro-displacements and meshing micro-displacements of different components are obtained. The sensitivity analysis of dynamic characteristics of planet carrier to nonlinear factors such as time-varying stiffness, meshing error, meshing clearance and external excitation are studied by finite difference method. It is found that the translational micro-displacement of planet carrier is most sensitive to external excitation, followed by the meshing error, and the sensitivity to other factors is weak.
