Abstract

Abstract: Aiming at the structural response of the tower under complex loads and different working conditions, the structural performance of a 2 MW large-scale horizontal-axis wind turbine tower is analyzed by adopting the method of building information modeling(BIM)+finite element analysis(FEA). Firstly, the BIM model of wind turbine is parametrically established and the tower load is analyzed and calculated, then the tower BIM model is converted to finite element model, and finally the tower is simulated and analyzed in finite element software ANSYS. The results show that the maximum stress of the tower occurs at the bottom and the maximum displacement at the top of the tower. The first six orders of the tower’s intrinsic frequency do not resonate with the tower, and the intrinsic frequency of the tower decreases with the increase of the tower height. The intrinsic frequency of the tower decreases with the increase of the top mass of the tower, and the change of the top mass of the tower has less effect on the stress and top displacement of the tower and more effect on the intrinsic frequency of the tower. The research show that the BIM+FEA method can provide new ideas for the structural safety analysis of wind turbine towers, which can provide safety warning in the design and operation and maintenance of wind turbine towers, and provide effective data and information for managers’ decision-making.
