Buckling Analysis on Large Wind Turbine Tower

Abstract:

The buckling of 2.5MW horizontal axis wind turbine tower tube (5.8m*3.2m*95.2m) is studied by theoretical analysis and numerical simulation. The buckling critical value of tower under axial force is found by theoretical method. The buckling modal of tower under axial force, wind pressure, bending moment and lateral force is simulated by ANSYS software. The buckling of tower with opening and frame at the bottom is also simulated by ANSYS software. The results show that both load and opening have influence on buckling performance, different load and opening have different impact to buckling of tower tube.
