Finite Element Analysis of 5MW Fiberglass and Carbon Fiber Wind Turbine Blade

Abstract:

Abstract: Base on finite element method of composite, take 5MW horizontal axis wind turbine blades as example, skin uses a mixture of fiberglass and carbon fiber as ply, spar caps and web adopt carbon fiber ply entirely to build the finite element model of the blade. The total weigh of the blade is 20.2 ton. Use Bladed software calculated the limit load of each cross-section, analyzed the stress distribution of each section and the modal characteristics of the blade, these provide a theoretical reference for the application of carbon fiber using on MW class wind turbine blade.
