摘要

由于风力发电机齿轮箱安装在柔性支承的塔架上,在复杂的工况下风力发电机塔架将产生弯曲摆动,严重影响着风力机齿轮传动系统的动态特性。考虑了风力机塔架的摆动与行星轮传动扭转振动的耦合效应,利用集中参数法建立柔性支承下的风力机行星轮传动系统的动力学分析模型,用Matlab进行数值求解。通过对国内1.5 MW主流风力机行星齿轮系统进行实例分析,得到了16 s时序随机风载下的行星齿轮系统各部件的位移历程。结果表明:在风力机运行中塔架产生剧烈振动,风力机塔架的振动加剧了风力机行星齿轮系统各部件的振动,在风力机行星齿轮设计时必须考虑塔架的柔性特性对风力机的影响。

Abstract

As the wind turbine gearbox mounted on a flexible support tower,the wind turbine tower will be bent and wiggled under the complex working conditions,and it will serious influence on the dynamic characteristic of the wind turbine gear transmission system. Considering the coupling effect of wind turbine tower swing and planetary wheel drive torsional vibration,by using the lumped parameter method,the dynamics analysis model of the flexible support of wind turbine planetary gear transmission system is established,and then the numerically solution is carried out with Matlab. By taking the instance analysis of the mainstream 1. 5MW wind turbine,the displacement progress of each part of planetary gear system under 16 seconds random time series wind load is got. The result shows that,in the process of wind turbine operation tower generates excessive vibration,and the vibration of the tower exacerbates the vibration of the components of wind turbine planetary gear system. Then,the impact of the flexible of the wind turbine tower must be considered in the wind turbine planetary gear design.
