针对半直驱风电行星齿轮系统的变速变载的特点，考虑风速变化引起的外部载荷激励，采用自回归滑动平均（ARMA）方法建立模拟风速模型，在考虑时变啮合刚度、啮合阻尼等因素的基础上，采用集中参数法建立了行星齿轮传动系统平移扭转耦合动力学模型。并采用四阶龙格库塔法，求解1．5 MW半直驱风力发电行星齿轮传动系统的动态响应。

Due to the variable speed and varia-ble load characteristics of semi direct drive wine turbines,external load excitation caused by varia-ble speed is considered and a simulated wind speed model is set up using the Auto Regressive and Moving Average Model (ARMA).A translational rotational coupling dynamic model of the planeta-ry gears transmission system is established using the lumped parameter method,which considers the time varying mesh stiffness and mesh damp-ing.The Runge Kutta method is used to derive the vibration dynamic response to the 1 .5 MW semi direct drive wind turbine system and accord-ing which the vibration performance is analyzed.
