| 摘 要： | 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。

| Abstract: | Due to the variable speed and variable load characteristics of semi-direct drive wine turbines, external load excitation caused by variable 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 planetary gears transmission system is established using the lumped-parameter method, which considers the time-varying mesh stiffness and mesh damping. The Runge-Kutta method is used to derive the vibration dynamic response to the 1.5 MW semi-direct drive wind turbine system and according which the vibration performance is analyzed. |
