为了获取目标三体船的侧体位置布局及设计宽度和排水量，对目标船型开展侧体布局对三体船的性能影响分析，重点分析侧体垂向位置和宽度变化对船体横稳性、阻力的影响。结果表明：侧体的垂向位置布置过低或过高都会对三体船型的横稳性不利；减小侧体宽度可减少排水量，对阻力有利，但对横稳性不利。在设计三体船侧体时，在确定了侧体相对于主体的纵向位置和横向位置后，需首先根据横稳性和阻力影响确定侧体相对于主体的布置高度，然后再根据横稳性和阻力影响进一步设计侧体宽度。本文建立的三体船侧体布局设计方法，可为工程三体船的侧体布局设计提供参考。
In order to obtain the side-hull position layout, design width and displacement of the target trimaran, the analysis was conducted on the impact of side-hull layout on the performance of the trimaran, with a focus on the effects of changes in the vertical position and width of the side-hull on the transverse stability and resistance of the hull. The results indicate that the side-hull to be located too lowly or too highly in vertical position will be detrimental to the transverse stability of the trimarans; Reducing the width of the side-hull can decrease the displacement, which is beneficial for resistance, but detrimental to transverse stability. When designing the side-hull of a trimaran, after determining the longitudinal and transverse positions of the side-hull relative to the main body, it is necessary to first determine the arrangement height of the side-hull relative to the main body based on the lateral stability and resistance effects, and then further design the width of the side-hull based on the lateral stability and resistance effects. The side-hull layout design method established in this article can provide reference for the side-hull layout design of trimaran in engineering.
