摘　　要：船舶碰撞损伤研究是船舶安全保障技术的基础性研究工作之一,而双壳船体结构碰撞损伤发展是预报与控制油船破损后溢油风险的重要理论基础。文章针对双壳船体结构碰撞损伤发展问题,设计了两个典型的碰撞工况,通过数值模拟的方法,对双壳船体结构破损发展阶段与损伤形态特征进行研究。以外壳和内壳破孔时刻点作为临界点,将双壳船体结构的碰撞损伤过程分为3个阶段,并对临界点对应的双壳船体损伤形态特征进行了分析。Research on ship collision injury is one of the basic research work of ship security technology, andthe damage development of a double hull structure is an important theoretical basis for prediction and control of oilspill risk in oil tanker impacting. Damage development of a double hull structure during impacting was concerned inthe article. And two typical collision conditions were designed. The damage development stages and damagemorphology on double hull structure were studied by the method of numerical simulation. It was used to divide thedamage process of double hull structure into three stages through two key points, the broken time of outer shell andinner shell. At the same time, the double hulldamage morphology in the critical points were analyzed
