Analytical Displacement Model of Wind Turbine Towers under Loading Conditions

The goal of this work is in twofold: 1) to determine the directional deformation (deflection) and bending stress 1.25 MW Suzlon wind turbine tower under loading conditions for different cross-sections through finite element analysis method; 2) develop validate analytical model allowing estimate same cross-sections. Wind shear force has been calculated prevailing direction structures integral equations, are then used as input 3-dimensional compute deflection stress. To improve estimation deflection, a mathematical developed based on cantilever beam theory. Results compared with those obtained from numerical method. found maximum at tip structure increasing hub height. indicate that square cross-section superior respect 0.064 mm. Numerical method verify results showing very less percentage error. Thus, new advantage estimating by just knowing average speed farm any structure.
