摘要

本文以同轴对转行星齿轮传动系统为研究对象，基于齿轮系统动力学和Lagrange方程，采用集中参数法建立了同轴对转系统的耦合动力学模型，模型中考虑了轮系的支撑刚度、弹性耦合和功率流向。在各个齿轮副的偏心误差、齿频误差和时变啮合刚度共同作用下，用数值分析方法得到了同轴对转系统的位移响应和速度响应等时域动态特性，并对比了定轴轮系与差动轮系的载荷分配，为同轴对转传动系统的动态性能优化与振动噪声研究提供了依据。

Abstract

Based on the method of gear system dynamics and Lagrange equation, a coupling dynamic model of the Co-axial Counter-rotating Epicyclic Transmissions(CCET) is built by lumped-parameter method, and the support stiffness, elastic coupling and power flow of the gear train is considered in the model. Under the action of the gear pair run-out error, meshing-frequency error and time-varying mesh stiffness together, time-domain dynamic characteristics about displacement response and speed response are achieved by numerical analysis method, and the load sharing is compared between ordinary gear train and differential gear train, which provides the basis for dynamic performance optimization and noise and vibration study of CCET.
