Abstract

The structural performance changes for blades under gravity, centrifugal force and aerodynamic force were considered, and 5 MW wind turbine blades were considered optimisation targets. A mathematical model for wind turbine blade optimisation was developed based on the classical laminate theory. The maximum stress at the laminate interface, maximum blade top displacement and laminate fibre angle were considered the optimisation objective, constraint variable and design variable, respectively. Then, the maximum displacement, Von_Mises stress and Tsai_Wu failure factor were compared and analyzed, and the best scheme was determined. The optimisation substantially reduced the tip displacement, maximum Von_Mises stress and Tsai_Wu failure factor, verifying the effectiveness of the optimisation method.
