THE STRUCTURAL ANALYSIS METHOD OF WIND TURBINE BLADE BASED ON MECHANICS OF COMPOSITE MATERIALS
摘要
Abstract
The method of blade section structural analysis is the key to the optimization design of wind turbine blades.In the existing research methods,the engineering mechanics calculation method based on the basic mechanics of materials has a fast computation speed,while its calculation accuracy is restricted for the approximate equivalent of material structures and attributes.Another method is the finite element method.It was widely used in the structural analysis of blade,but for high time-consuming the modeling and calculating,it's not easily used in the optimization design of wind turbine blades.Based on the study of the laminate structure of the blades,the new method and formulas for calculating the tensile and shear stress of blade sections is developed.Taking a 1.5 MW blade as an example,the structural strength of the blade is studied with the ultimate loads of the blade,and compared with the test result.The feasibility of the new method was verified.关键词
