摘　　要：应用Theodorsen二维翼型的经典颤振理论,借助ANSYS开发平台Matrix 27用户自定义单元,建立了立轴风力机叶片梁模型有限元格式的气动质量矩阵、气动阻尼矩阵和气动刚度矩阵及风力机动力学分析的有限元方程,对兆瓦级Darriaus型立轴风力机进行气动弹性稳定性分析。Based on Theodorsen＇ s classical flutter theory of 2D aerofoil, using Matrix 27 user-defined element of ANSYS development platform, aerodynamic mass matrix, aerodynamic damping matrix and aerodynamic stiffness matrix of blade with finite element format of beam model of vertical axis wind turbine and finite element dynamic equations of wind turbine were given. Aeroelastie stability analysis on 1MW Darriaus vertical axis wind turbine was done.
