摘要
恶劣海况易导致航行船舶碰撞事故,实际上船舶碰撞过程作为海上波浪载荷作用和碰撞力影响的耦合。根据非线性的有限元法,构建充分考虑波浪作用影响碰撞船舶模型,利用数据仿真法对船舶碰撞过程进行模拟。比较是否有波浪作用的船舶碰撞结果,并分析波浪的入射角、周期和波浪高度致使被撞船舶船体舷侧结构损伤程度的影响。结果证明:一定情形下波浪作用对船舶碰撞全过程具有较大的不利影响,从船舶工程角度提出避免风险措施。
Bad sea conditions can easily lead to ship collision accidents,in fact,the ship collision process is the coupling of wave load and collision force at sea.According to the nonlinear finite element method,the ship collision model is fully considered,and the data simulation method is used to simulate the ship collision process.The collision results of ships with or without wave action are compared,and the influence of wave incident angle,period and wave height on the damage degree of ship hull side structure is analyzed.The analysis results show that under certain circumstances,the wave action has a great adverse effect on the whole process of ship collision,and the risk avoidance measures are put forward from the point of view of ship engineering.
