摘要
针对海上风机数量的增多导致船舶碰撞风险增加的问题,提出了一种海上风力发电机单桩基础防护设施。应用ANSYS/LS-DYNA软件模拟4000t近海散货船分别以0.5m/s和1.0m/s的速度与防护设施横舱壁位置、无骨架位置的碰撞过程,并计算了结构的应力、位移、碰撞力曲线和碰撞能量。结果表明:不同工况下被撞击位置的内部结构均未发生结构失效,撞击后防撞结构性能良好,验证了该防护设施的可靠性。
Aiming at the problem that the increase in the number of offshore wind turbines leads to the increased risk of ship collision, a monopile foundation protection facility for offshore wind turbines is proposed. The ANSYS/LS-DYNA software is used to simulate the collision process of a 4 000 t offshore bulk carrier with protective facilities at speeds of 0.5 m/s and 1.0 m/s. The stress, displacement, collision force curve, and collision energy of the structure are calculated. The results show that the internal structure of the impacted position has no structural failure under different working conditions, and the anti-collision structure has good performance after the impact, which verifies the anti-collision performance of the protective facility.
