摘要
由于风力发电机偏航系统工作环境复杂,风向的变化在启动与停止间不断切换,且承受较大的冲击载荷,加之风力发电机为高空设备,安装、维护与检修困难,对其使用寿命及运行稳定性都具有较高的要求。根据多体系统动力学理论,利用UG建立风力发电机偏航系统齿轮副简化模型。针对该模型,使用多体系统动力学软件ADAMS分析研究风力发电机偏航启动过程中偏航齿轮传动系统的动力学特性。通过仿真计算,得到了动态啮合力的时程曲线,揭示了偏航齿轮启动时的动态特性。
Due to the complex working conditions and time-varying wind direction,the yaw system of wind turbine starts and stops frequently and is under large impact load. As a high-altitude equipment,the cost of installation and maintenance is quite high. So the yaw system has a high requirement for useful life and ride quality.The simplified dynamic model of yaw gears of wind turbine is estamblished by UG according to The dynamics of multi-body system. The danymic characteristics of the yaw gear system of wind turbine during starting procedure is analyzed by ADAMS. The dynamic characteristics of the yaw gear system of wind turbine during starting procedure is reviewed and the time-domain waveform of meshing force is obtained by simulation.
