Finite Element Analysis for Composite Blade Structure of Large Wind Turbine
摘要
Abstract
Composite material has higher ratio of strength to weight and ratio of stiffness to weight than other ma-terials,and may change its performance within a certain range to raise its bearing capacity by layer lay-up optimiza-tion design. Composite materials have been successfully applied in the design of large wind turbine blade. Blade is one of the most important parts of wind turbine and bears more complicated loading. Well-designed blade can gain higher power coefficient and better economic profit. From the state of art and trend of wind power generation in the world,the installed capacity increases year by year. Considering its environmental protection and renewability,there is a huge space for development of wind power generation. Finite element analysis of a composite blade was performed in this paper with considering the work characteristics of the blade. This work can be em-ployed to evaluate the reliability and economic efficiency in design of blade structure.关键词
