摘要: 由于风速的随机性特点,使得风电齿轮箱长期处于较为复杂的变载荷作用下而产生振动,这些振动将会引起齿轮箱内部结构的损坏.为了更好地对齿轮箱进行动力学分析,将风电齿轮箱传动系统分解为三级齿轮传动,采用集中质量法,在直齿轮、斜齿轮和行星齿轮动力学模型的基础上,建立了整个齿轮箱传动系统的动力学模型;并在考虑齿轮啮合刚度、啮合阻尼、啮合误差、偏心量、弯扭耦合、自身重力以及支撑轴承等因素的共同作用下,利用拉格朗日方程推导了整个传动系统的动力学方程.为今后分析兆瓦级风电齿轮箱传动系统的固有特性、动态响应等动力学特性奠定了一定的基础.

Abstract: Due to the random characteristics of wind speed, the transmission system in wind turbine gearbox would produce complex vibration, which can cause internal structure fatigue of the drive system. In order to analyze the performance of the gearbox, the wind turbine gearbox system was divided into threeclass gear transmission, and the dynamical models of spur gear, helical gear and planetary gear were built. On this basis, the dynamical model of the whole wind turbine gearbox system was established. The vibration differential equations of the drive system were derived through the Lagrange’s equation, considering the meshing stiffness, meshing damping, comprehensive meshing error, eccentricity, gravity, bendingtorsional coupling and support bearing. The model provides some theoretical reference for the characteristic analysis and vibration control of similar wind turbine gearbox system.

Key words: wind turbine, gearbox, gear system, coupling vibration, dynamical model
