以Wigley船型作为基准模型,建立单体船、双体船、三体船和五体船等多体船的计算模型,对比分析了单体船、双体船、三体船、五体船的水动力特性,并分析了双体船片体间的兴波干扰作用和双片体对纵摇和垂荡运动的影响。综合来看,单体船在迎浪航行时有良好的耐波性,双体船虽然在迎浪时可能会遭遇横跨湿甲板波浪的砰击,但总体来看耐波性一般也良好。三体船型由于侧体安装位置靠后,因此极易发生埋艏现象。五体船型的耐波性在4种船型中较优,其在波浪中的纵摇与垂向运动响应最不剧烈,但五体船主体和各侧体之间较差的兴波能力仍会给总阻力等带来不利影响。
In this paper, Wigley hull type is taken as the reference model, and the calculation models of multi-hull ship for monohull, catamaran, trimaran and pentamaran are established. The hydrodynamic characteristics of monohull, catamaran, trimaran and pentamaran are compared and analyzed, and the wave interference between the two piece hulls and the influence of the two piece hulls on pitch and heave motion are also analyzed. It is found that the monohull has good seakeeping when navigating in the upstream direction. Although the catamaran may suffer slamming across wet deck waves in the upstream direction, but they also have good seakeeping.The trimaran is very prone to plough-in because its side hull is installed backwards.The pentamaran has the best seakeeping among the four types, and its response to pitch and heave motion in waves is the least intense. However, the poor wave-making ability between the main body and each side of the pentamaran still brings adverse effects on the total resistance.
