风载荷对单柱式海上风力机船舶碰撞影响研究
Research the influence of wind load on the collision of ship and monopile offshore wind turbine
摘要
Abstract
With the development and utilization of offshore wind power, the collision risk between the ship and offshore wind turbine is gradually rising.Therefore,the nonlinear finite element LS-DYNA sim-ulation software is used to simulate the collision process of a 5000 t ship at a speed of 2 m/s with a typical 3 MW monopile offshore wind turbine and to study the influence of the wind load on the collision between ship and monopile wind turbine.Through the analysis of collision force,displacement and acceleration of the top in tower and equivalent plastic strain at the tower,the result can be obtained as follow:the wind load on the wind turbine has great influence on dynamic response of collision; relative difference of the collision force,displacement and acceleration of the top in tower and equivalent plastic strain at the tower are about 1%,10.9%,17.5%and 3.05%,respectively.The direction of wind load has also great in-fluence on dynamic response of collision; in the different direction of the wind load, the maximum and minimum of the collision force,displacement and acceleration of the top in tower and equivalent plastic strain at the tower are about 28.5%,57%,62.5%and 28.5%,respectively.In the different direction of the wind load,the maximum and minimum of longitudinal displacement are 0.505 m and 0.0393 m, respectively.The results of the study can provide theoretical reference to provide the offshore wind turbine in the collision.关键词
