摘要
以海上风力机塔架为研究对象,给出了考虑几何非线性的塔架结构控制方程,采用SolidWorks软件完成了塔架三维建模,基于ANSYS软件进行了有限元网格的无关性验证。计算并分析了不同平均风速下塔架的位移和Mises应力响应,揭示了塔架最大位移和最大Mises应力随平均风速变化的规律。这可为风机塔架的运行安全和可靠性设计提供指导。
Taking an offshore wind turbine tower as the research object,the control equations of the tower structure with geometric nonlinearity considered are given,and a 3 D modeling of tower is achieved by using SolidWorks software. Besides,the independent verification of finite element mesh is carried out based on ANSYS software. The response of displacement and Mises stress of the tower under different average wind speeds is calculated and analyzed,and the varying rules of the maximum displacement and maximum Mises stress of the tower with the average wind speed are revealed,which can provide guidance for operational safety and reliability design of wind turbine tower.
