摘要：  针对五体船前后侧体的不同位置，分析了侧体布局对五体船纵向运动的影响.采用Rankine面元法计算了五体船在规则波中前后侧体12种布置方案下的纵向运动响应RAO，分析了前后侧体纵向、垂向位置变化对船体运动的影响规律.考虑非线性因素，在非规则波中计算了五体船运动响应时历，比较了高、低航速时侧体位置变化对运动响应有义值的影响特点.分析结果表明：五体船前后侧体布局对运动的影响与航速密切相关，后侧体在低航速时靠近船中布置、高航速时靠近船尾布置更有利于减小船体垂荡运动；通过降低前侧体垂向高度和靠近船首布置有利于减小五体船垂荡和纵摇运动.

Abstract: For different position of side hulls of pentamaran, the influence of side hulls layout on longitudinal motion was studied. Rankine panel method was used to calculate the motion response RAO of pentamaran with 12 side hulls layout schemes in regular wave and the effect of side hulls layout relative to main hull on motion was analyzed according to the results. Considering the nonlinear factor, the motion history of pentamaran in irregular wave was calculated and the statistic significant values of heave and pitch motion were compared. The influence of side hulls layout of pentamaran on longitudinal motion is closely related to sailing speed. Sailing at lower speed, the heave motion of pentamaran could decrease when the back side hulls lying near midship and converse trend appears at high speed. Reducing the height and lying near bow of front side hulls could help improve the heave and pitch motion of pentamaran.

Key words: pentamaran, side hulls layout, longitudinal motion, nonlinear
