摘    要:针对船舶碰撞造成的船体结构安全性问题,基于SOLAS规范中关于等效安全度的概念,提出一种结构设计方法.应用非线性动力分析法计算船舶遭遇碰撞破损时的结构极限吸能,以某多功能运输船为算例,通过对其舷侧结构的重新布置设计,选取2种船艏型式和8种撞击位置,比较其结构极限吸能能力.研究结果表明:该设计方案在满足SLOAS规范中破舱稳性要求的基础上,提供了更大的货舱装载能力和使用的灵活性,可以作为此类船型设计的参考.

关 键 词:船舶碰撞  破舱稳性  等效安全度  结构设计  结构吸能

Abstract:On the basis of the concept of the same degree of safty,a method of structure design was provided.Non-linear dynamic analysis was applied to calculate the ultimate energy absorption of structure.Taking a general cargo whose broadside structure would be re-designed as example,the ultimate energy absorption capacity was compared according to the calculated results in cases of two types of vessel bow and eight impact locations.The results indicate that the design not only meet the requirements of damage stability in the SOLAS regulation,but also provide more loading capacity and reduce operational restrictions,which can be the reference for designing this kind of vessels.
Keywords:ship collision  damage stability  same degree safety  structural design  energy absorption
