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两侧片体来弥补 .采用静力学方法对多体船横倾状态下的受力情况进行分析 ,建立了多体船完整稳性的计算模型 .以一多体船方案为例进行完整稳性计算 ,分析了侧体跨距、排水量等参数对静稳性臂的影响以及静稳性曲线的特征 ,并对不同形式多体船的稳性特征进行了比较 .分析显示 ,多体船的横稳性主要受到侧体的排水量和横向位置的影响 。The slender monohull offers 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 intact stability. With static method, this paper presented some research work on the mechanics analysis, the intact stability characteristics of multi hulls and the solution to the calculation of transverse stability. Based on the results of some calculation, the character of static stability arm and the difference between trimaran and pentamaran were analyzed. The results show that the side hull transverse position and displacement have great influence on the intact stability, and the validity of the initial stability calculation result is less than that of the monohull. The conclusion of the work is useful for the research and design of multi hulls.
