摘　　要：针对水介质环境及水介质环境下速度、角度对船舶的结构响应影响机理,利用船舶CFD技术及非线性有限元法模拟水介质中的船-冰碰撞。对比研究船舶在有、无水介质环境下结构响应特性及水介质环境下不同速度、角度的动态结构响应特性,揭示了船舶在不同工况下的损伤变形及碰撞力规律,得到了有、无水介质环境、碰撞速度、碰撞角度等因素对船-冰碰撞的影响机理,为船舶抗冰载荷设计提供参考。According to the influence mechanism of velocity and angle on ship structure response under water medium environment and water medium environment,the Ship-ice collision in water medium is simulated by ship CFD technology and nonlinear finite element method.By comparing the structure response characteristics of ships under the condition of water-free medium and the dynamic structural response characteristics of different velocities and angles,the paper reveals the damage deformation and collision force law of ships under different working conditions,and obtains the influence mechanism of Water-free medium environment,collision speed and collision angle on Ship-ice Collision.It provides a reference for ship anti-icing load design.
