Analysis of Dynamic Responses of Collisions between Three Types of Offshore Wind Turbine Foundations and Ship

Abstract

Abstract: A model of 5 MW offshore wind turbine and ship collision was established, and the nonlinear dynamics theory was used to compare the impact resistances of the three kinds of offshore wind turbine supporting foundations under the impact of different speed ships and the response characteristics of the wind turbines on the tops of the tower. The results show that the displacement and acceleration responses of the single-column foundation offshore wind turbines are more obvious than that of others. In the processes of collision,the collision area is deformed, and the casing pipe and X-Joints have obvious strains. These parts should be reinforced during the design proceses. From the impact depths and contact forces of the offshore wind turbine supports, the impact resistance of the jacket foundation is the best.

Key words: offshore wind turbine, jacket, tripod, monopole, collision, dynamic response

摘要： 建立了5 MW海上风力机与船舶碰撞模型，采用非线性动力学理论，对比和分析3种海上风力机支撑基础在不同速度船舶撞击下结构的抗撞性能及塔顶的风力机响应特性。结果表明：相对于三角架基础和导管架基础，单柱基础海上风力机位移和加速度响应更加明显；碰撞过程中，不仅碰撞区域发生变形，而且管桩连接部位、斜撑杆交叉处也有较明显的应变产生，应在设计过程中对这些部位进行加固。由海上风力机支撑基础撞击深度和接触力可知，导管架基础的抗撞性能最好。
