Notes:
The composite rotor blades have been widely used as an important part of the wind powergeneration systems because the strength, stiffness, durability and vibration of composite materials areall excellent. In composite laminated blades, the static and dynamic aeroelasticity tailoring can beperformed by controlling laminate angle or stacking sequence. In this paper, the fluid-structurecoupled analyses of 10kW wind turbine blades has been performed by means of the full couplingbetween CFD and CSD based finite element methods. Fiber enforced composites fabricated withthree types of stacking sequences were also studied. First the centrifugal force was considered for thenonlinear static analyses of the wind turbine so as to predict the deformation of tip point in the lengthdirection and maximum stress in the root of a wind turbine. And then, the aeroelastic staticdeformation was taken into account with fluid-structure interaction analysis of the wind turbine. TheArbitrary Lagrangian Eulerian Coordinate was used to compute fluid structure interaction analysis ofthe wind turbine by using ADINA program. The displacement and stress increased apparently withthe increment of aerodynamic force, but under the condition of maximum rotation speed 140RPM ofthe wind turbine, the displacement and stress were in the range of safety
