Description:
The paper presents the modal analysis of a wind turbine type WTB type GE 1.5sle, scale 1:5, obtained by numerical modeling. 3D virtual model of blade was designed in CatiaV5 and imported in Abaqus software. The structure was built up as GFRP laminated composite with 5 layers and the materials properties were obtained from tensile test. In the first stage, the modes and natural frequencies of the blade were modelled as a composite structure reinforced with glass fibre fabric. In the second step the modal response of the blade having delaminated areas was analyzed. The results emphasized that the values of the natural frequencies change both in the analysis of the free structure and the fixed structure.
