摘要

基于多体系统动力学和升力线气动模型

Abstract

Based on multi-body system dynamics and lift line aerodynamic model

considering dynamic stall and aeroelastic coupling of flexible back-swept blades

a wind turbine aeroelastic coupling model is established to study the effect of extreme operating gusts and duration of the gusts on the aerodynamic performance of a 5 MW back-swept wind turbines blades. The results show that extreme operating gusts have a great influence on aerodynamic characteristics

such as the flapwise root moment

power

angle of attack

lift coefficient and thrust. The research work has an important significance for wind turbine’s structural optimization and fatigue life design.
