摘　　要：多体船的设计概念是通过采用大长宽比的主船体来有效减小兴波阻力,而由此带来的稳性损失由侧体来弥补.文章以一多体船方案为例进行破舱稳性计算,分析了多体船侧体参数对多体船破舱稳性的影响,并比较分析了在相同破损状况下三体船与五体船的破舱稳性.分析显示,侧体中心与主船体中心的横距越大,侧体中心离主船体中心的纵距越小,其破舱稳性就越好.The slender multi-hulls offer the potentiality in reducing both the wave resistance and often the total resistance, but it is laterally unstable. So side hulls play an important role in the performance of damaged stability. In this paper, based on the results of some calculation, the character of damaged stability and the difference between trimaran and pentamaran are analyzed The results show that the larger the side hull transverse position and the nearer longitudinal distance between the centre of side hull and the centre of main hull, the better its damaged stability is.
