摘要
塔架支撑位于空中的风力发电系统,塔架与基础相连,承受风力发电系统运行引起的各种载荷,同时传递这些载荷到基础,使整个风力发电机组能稳定可靠运行。对20kW风力发电组的塔架进行了三维建模,根据动力学特性确定塔架所受的各种载荷。利用Ansys软件对塔架进行网格划分并施加边界条件,通过有限元法准确计算出塔架的应力变化,对塔架的强度、刚度、塔架的最大位移变形量进行了仿真分析,从而为塔架的优化设计提供依据,并将所设计的20kW塔架应用于实际生产中,取得了良好的经济效益。
The tower is to support the overhead wind power generation system,which is connected to base,bearing all kinds of loads from wind power generating system,and transfer these loads to the foundation so that the wind turbine can run stably and reliably.In this article 3D modeling,for tower of the 20kW wind power generator is done and loads on the tower is determined according to the dynamic characteristics.Then by applying software Ansys meshing for the tower is made with boundary conditions being imposed,and the strength,stiffness,maximum displacement of the tower deformation are simulated and analyzed,which provides the basis for the optimization design of the tower,thus good economic benefits is achieved after being applied to the actual productio.
