Abstract： Anti-collision characteristics of the offshore wind turbine is one of the factors to be considered in its structure design. By using MSC.Dytran, a nonlinear finite element code for dynamic response analysis, the dynamic processes of an offshore wind turbine stricken by a ship of 5000 DWT displacement in the lateral direction at different initial velocities are simulated. The structural damage characteristics of the offshore wind turbine, the curves of collision force vs. penetration, the curves of energy transformation and other relevant data are obtained. According to the numerical simulation results, the structural anti-collision characteristics of the offshore wind turbine and its structural deformation characteristics in the collision process are analyzed, and the influences on the structural damage due to different striking energy are also discussed.
