摘　　要：针对风力发电机齿轮箱中的行星传动系统,在考虑啮合误差与质量偏心的前提下,建立了18自由度的动力学微分方程。使用Runge-Kutta算法,计算各个构件在变载荷下分别存在不同程度的质量偏心时的动力学响应。计算结果表明:时变载荷主要影响行星架、行星轮以及太阳轮的扭转振动;对于平移振动,由于时变载荷、质量偏心等因素的影响,啮合频率处存在明显的边频带;对于1.5 MW风力发电机齿轮箱行星传动系统,额定工况下行星架、行星轮与太阳轮的质量偏心对系统动力学响应的影响较小。Mass eccentricity and meshing error are incorporated into a planetary transmission system of large wind turbine and the dynamic model with 18 degrees of freedom is built using lumped-parameter method. The time-varying load caused by chaotic wind turbine is obtained with Weibull model. The equations are solved by Runge-Kutta method. The simulation results demonstrate that the time-varying load primarily affects the torsional vibration of the planet carrier, planet gear, and sun gear. As for translational vibration, there is an obvious sideband at the meshing frequency due to the influence of time-varying load, mass eccentricity, and other factors. The mass eccentricity of the planetary frame, the planetary gear, and the sun gear have less impacts on the dynamic response of the 1.5 MW wind turbine gearbox planetary transmission system.
