| 摘 要： | 随着大型油轮及液化气船的相继开发和应用,载液货船在碰撞中的损伤问题越来越备受关注.采用大型动力非线性有限元软件ABAQUSXEXPLICIT,对空载和80%装载两种状态下的碰撞动力学过程进行了数值仿真计算.通过两种装载状态下碰撞力载荷、舷侧各构件(舷侧外板、内板及之间十字隔板)损伤变形模式、范围及塑性变形能吸收等的对比分析发现:舱内液货对舷侧外板影响不大,但十字隔板及舷侧内板在损伤范围和能量吸收上均得到了很大的提升,尤其以与液货接触的舷侧内板最为显著.这说明舱内液货对船舶舷侧碰撞性能影响极为不利,在结构设计时必须予以充分考虑.

| Abstract: | With the successive development and application of large oil tanker and liquefied gas carrier,the damage of the ship carrying liquid cargo during collision accident is of a more and more concern.Employing the general dynamic finite element package ABAQUSEXPLICIT,the dynamic process of collision with both the case of liquid tank without oil and 80% filled is simulated.The comparisons on impact resistance,damage deformation mode,damage range and plastic deformation energy of the double-skin side structure's ... |
