Load Analysis And Preliminary Structural Design On Wind Turbine Blade

The method study of structural design and analysis for wind turbine blade is one of key technical works during the large scale domestic wind turbine has been developed independent and produced.Based on variety of wind turbine blade design theories,the method of structural design for wind turbine are studied.First,analyzes the process of preliminary design of the blades,applying Programming PROPID design aerodynamic shape of the blades.Then,based on understanding of the relevant IEC standards and the blade design,a simulation model has been set up,analyze the load on blades in specific wind conditions.Reference the structural design theory for wind turbine blades,a structure design methodology has been put forward in this paper.Applying this method on structural design for 1.5MW wind turbine blades,complete the static structural design and blade checking.
