摘要

海上风电站的抗撞特性是设计中必须考虑的要素之一。利用非线性有限元动态响应分析程序MSC.Dytran模拟了一艘5000吨船舶以不同速度侧向撞击海上风电站的动态过程，得到了风电站的结构损伤特性、碰撞力-撞深曲线、能量转化曲线及其它相关数据。根据数值仿真计算结果，分析了风电站的结构抗撞特性，并对撞击过程中风电站的结构变形特征以及撞击能量对风电站结构损伤的影响程度进行了探讨。

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.
