| 摘 要： | 为研究舱内液货对船体结构损伤机理的影响,利用数值仿真软件MSC.Dytran,计算出背液板架流固耦合力、碰撞力、损伤变形以及能量吸收等,并与背空板架进行了对比分析.结果表明,背液板架的损伤机理明显区别于背空板架,流固耦合力使得结构的变形模式发生了改变、碰撞力增加、极限撞深减小.

| Abstract: | Recently,scholars have carried out many research works about ship collision.However,these works always ignore the influence of the liquid cargo during ship collision.In this paper,comparison analysis was performed for framing panel backed with liquid and backed with air in damage mechanism and collision force as well as energy absorption.The results show that the liquid fluid has a remarkable effect on the structure damage mechanism.Compared with the calculation results of model for framing panel backed wit... |
