基于涡尾迹方法的风力机载荷与响应计算
Wind turbine aerodynamic load and response prediction based on vortex wake method
摘要
Abstract
The vortex wake method is used to predict the quasi-steady aerodynamic forces, which are subsequently input to the Leishman-Beddoes dynamic model to calculate the unsteady aerodynamic forces. The structural dynamic equations are obtained for wind turbine rotor. The modal analysis of wind turbine rotor is calculated based on blades flapwise stiffness, edgewise stiffness, and mass properties of hub and tower structure using FEM approach. The wind turbine aerodynamic forces and response calculation model is constructed by adding the contribution of blade vibration speeds to unsteady aerodynamic forces. The time-responses of aerodynamic forces, vibration deflection and vibration speed are calculated both for the NREL Phase VI turbine and for a 1.5 MW wind turbine, showing certain useful results and conclusion with analysis in detail to some extent.关键词
