摘要

为了使风力发电机组具有较稳定的工作性能

提高其风力机叶片翼型的使用寿命

对叶片翼型进行了强度分析。以NACA0015(对称翼型)叶片翼型为研究对象

对其建立了三维模型

设定了旋转域及相关边界条件

采用流固耦合方法

利用ANSYS-CFX软件对垂直轴风力机叶片翼型进行了气动性能分析。结果表明

在常温常压且风速10 m/s

转速80 r/min的工况下

位于叶片后缘处变形最大为3.961×10-4mm

不同位置变形量与厚度呈线性关系

适当增大叶片翼型后缘厚度的方法

能够增强叶片翼型的强度

使其具有很好的抗变形能力。因此

增加叶片翼型厚度可减小叶片翼型变形量

提高叶片翼型的使用寿命。

Abstract

Aiming at making the wind turbine have more stable work performances and prolonging the service life of the wind turbine blades

strength analysis on the wind turbine blade airfoil was carried out. By taking the NACA0015 blade( symmetric airfoil) as the object

its three-dimensional model was established and the rotation field and associated boundary conditions were set. The fluid solid coupling method was adopted to conduct aerodynamic performance analysis on the vertical axis wind turbine blade

by using the ANSYS-CFX software. The results show that

at room temperature and atmospheric pressure

with wind speed of 10 m / s and rotor speed of 80 r / min

the maximum deformation of the blade lied in the blade trailing edge out

with amount of 3. 961 × 10- 4mm. The deformation amount had a liner relationship with the blade thickness. Properly increasing the airfoil trailing edge thickness can enhance the airfoil strength

making it have good deformation resistance. Therefore

increasing the blade thickness can reduce the blade deformation and prolong the blade's service life.
