摘要
在对风力机空气动力学分析的基础上,对液压变桨执行机构的机械动力学做了深入研究,得到了液压变桨执行机构机械动力学数学模型。利用动力学仿真软件Adams对一台2MW风力机液压变桨执行机构进行动力学仿真实验,仿真结果表明,在风力机变桨过程中,通过对执行机构角速度、角加速度、活塞杆三个方向的受力比较分析,为液压变桨执行机构的优化设计和疲劳寿命分析提供理论支持。
Based on analysis of the air dynamics for wind turbine, the analysis lays groundwork for a further study on machine dynamics of hydraulic variable- pitch actuator,and the mechanical dynamic mathematical model of hydraulic variable pitch actuator is obtained.The dynamic simulation experiment of hydraulic variable-pitch actuator for 2MW wind turbine is conducted by using Adams, Simulation results show that the process of variable pitch for wind turbine provide theoretical support for the optimization design and fatigue life analysis of hydraulic variable-pitch actuator,which is achieved through the comparison and analysis of angular velocity, the angular acceleration of the actuator and the stress of three directions for piston rod.
