Analysis of deflection and stress for large wind turbine blade under different average wind speeds
摘要
Abstract
Deflection and stress of wind turbine blade under different average wind speeds were analyzed by finite element analysis software. Different average wind speeds were simulated by davenport spectrum of fluctuating wind, and deflection and stress distribution of each part of blades were calculated. The results indicate that the waving of blade is the main form of vibration, and that the waving amplitude increases with the wind speed, and that the mises stress is primarily in the middle of windward side of the blade, which provides technical references for safety design of wind turbine blades.关键词
