| 中文摘要: |
| 以风力发电机组为研究对象,采用动量叶素理论计算叶片在不同风速下的气动载荷,在三维软件Solidworks中建立了叶片、轮毂、机舱和塔架等关键功能部件的三维模型,在Ansys中对叶片和塔架进行柔性化处理,生成叶片和塔架的MNF文件,建立了风力机组关键功能部件的ADAMS刚柔耦合多体系统动力学模型.将计算的载荷均匀加载到风力机组的叶片上,对风力机在风速由5 m/s变化到25 m/s的过程进行仿真,得到叶片和塔架的振动变形特性曲线.该仿真能够很好地模拟风力机的振动变形特性,为风力机的虚拟样机仿真提供了一种可行的方法. |
| 英文摘要: |
| In the article,the blade element momentum theory was used for the calculation of aerodynamic load of blade under the different wind velocities.A 3D model of key functional components such as blade,tower,hub and nacelle were modeled in Solidworks,the MNF files of blade and tower were gained in finite element analysis software after flexible processing,and the rigid-flexible multi-body dynamic model of the wind turbine’s key components was created in ADAMS.Through the simulation of the model under constant rotate speed,kinematic and dynamic curves were obtained while the wind speed rose from 5 m/s to 25 m/s.This simulation imitates the vibration performance ideally,which provides a feasible method for the virtual prototype simulation of wind turbines. |
