Abstract:
In view of the special structure, complex stress and easy failure of flange-bolt of wind turbine tower, the fatigue reliability of high strength bolted joints under combined effect of wind and ice was studied. Firstly, the wind speed time history was generated by harmonic superposition method, and ice force time history acting on wind power tower was calculated according to generalized ice force function. Then, ANSYS was used to build the wind tower model, and the generated wind load and dynamic ice load were applied to obtain the stress time history curve at the center of flange. Based on Schmidt-Neuper theory and finite element method, the flange bolt structure was calculated, and the relationship between flange load and bolt stress was obtained. The stress time history curve of bolt under external load was obtained by MATLAB polynomial fitting. Finally, based on the cumulative damage theory, the fatigue reliability of bolts under different load conditions was calculated, and the effects of preload, bolt position and ice speed on the fatigue reliability were discussed. The results show that after considering the ice load, the fatigue reliability of the bolt decreases, and the effect of ice load on the fatigue reliability of bolt can not be ignored. The preload has great influence on bolt fatigue reliability under wind load, but has little influence on bolt fatigue reliability under ice load. The location of bolts has great influence on the fatigue reliability of bolts under various load conditions, and has the most obvious influence on the fatigue reliability of bolts under ice load. When the external load on the flange is greater than the load needed to separate the bolted joints, the stress amplitude of the bolts will be increased, thus the fatigue reliability of the bolts will be reduced. The main factor affecting the fatigue reliability of bolts under ice load is tower resonance caused by ice-induced action.
