摘　　要：为探究制造误差对复式行星传动系统动态特性的影响,基于势能法得到了系统的时变啮合刚度,综合考虑阻尼、时变啮合刚度、制造偏心误差等因素,采用集中质量法建立了传动系统的平移-扭转耦合动力学模型,利用Newmark-β积分法求解了系统的动态响应,分析了单构件制造偏心误差及多构件误差耦合作用对系统啮合力、啮合力幅值波动及太阳轮中心浮动轨迹的影响。分析结果表明,多构件误差的耦合作用会使啮合力波动范围增大,低阶倍频幅值有所上升;偏心误差使系统的啮合力幅值波动呈上升趋势,其中受短行星轮误差影响较大;双行星轮误差的同时作用加剧了太阳轮浮动。To investigate the impact of manufacturing errors on the dynamic characteristics of a compound planetary transmission system,the time-varying meshing stiffness of the system was obtained based on the potential energy method.Taking into account factors such as damping,time-varying meshing stiffness,and manufacturing eccentricity error,a translation-torsion coupling dynamic model of the transmission system was established using the centralized mass method.The Newmark-βthe integration method solved the dynamic response of the system,and analyzed the effects of single component manufacturing eccentricity error and multi component error coupling on the system meshing force,amplitude fluctuation of meshing force,and the floating trajectory of the solar wheel center.The analysis results indicate that the coupling effect of multi component errors will increase the range of meshing force fluctuations and the amplitude of lower order harmonics to some extent;The eccentricity error causes an upward trend in the amplitude fluctuation of the meshing force of the system,which is greatly affected by the error of the short planetary gear;The simultaneous effect of double planet wheel errors exacerbates the floating of the solar wheel.
