Modal Analysis of Wind Turbine Blade Made of Composite laminated plates

Abstract

Composite laminated plate structure has been widely used in wind turbine blade. In this paper, combining composite laminated plate blade's characteristics of hierarchical structure, based on finite element analysis software ANSYS, laminated shell element is used to create finite element model, and the finite element modal analysis is made to obtain modal parameters and the natural frequency spectrum of blade. The results have laid a foundation for further study of the wind turbine blade's vibration, structural dynamics and other issues.
