摘要
以5MW风力机叶片为研究对象,首先通过PROFILI软件导出所需翼型的数据,其次使用MATLAB软件对所需的翼型数据进行二次开发处理,再次通过SolidWorks软件快速建立风力机叶片三维壳体模型。进一步通过流体力学方法计算出额定风场下风力机叶片表面的气动载荷,并且通过ANSYS软件对风力机叶片进行静力学分析及预应力下的模态分析。通过计算出风力机叶片的各阶振型,分析计算结果预测风力机叶片最容易发生疲劳失效的部位,采取可靠主动措施,提高风力机叶片强度。
This paper takes 5MW wind turbine blade as the research object.Firstly,the data of the required airfoil is derived through PROFILI software.Secondly,the required airfoil data is secondary developed and processed by MATLAB software.Thirdly,the three-dimensional shell model of wind turbine blade is quickly established through SolidWorks software.Further,the aerodynamic load on the surface of wind turbine blade under rated wind field is calculated by hydrodynamics method,and the static analysis and modal analysis of wind turbine blade under prestress are carried out by ANSYS software.By calculating the vibration modes of each step of the wind turbine blade,analyzing the calculation results,predicting the most prone parts of the wind turbine blade to fatigue failure,and taking reliable and active measures to improve the strength of the wind turbine blade.
