摘　　要：基于二维半理论的计算软件TRIMARAN研究了侧体纵向、横向位置的变化对三体船运动响应的影响,同时研究了船体横摇惯性半径对三体船横摇性能的影响,从而提出一套三体船侧体位置优化方案。通过在低速和高速两种情况下,对三体船侧体纵向、横向位置的变化对三体船的运动响应分析,可以看出:低航速下侧体应布置于靠近主体船艏的位置,有利于三体船运动性能的提升,高航速下则应将侧体放置于主体船尾。同时,根据横摇惯性半径对三体船横摇性能的影响研究表明:三体船的横摇半径越小越能增加三体船的横摇稳定性。The response of trimaran to the change of the vertical and horizontal position of the side-hull is researched by TRIMARAN which is based on 2.5D potential theory. The influence of the hull roll radius on the rolling performance of the trimaran is also studied to propose a set of schemes for the optimization of the side- hull location. The analysis of the results under low-speed and high-speed condition shows that the side-hull should be located close to stem under the low-speed condition in order to improve movement capability of trimaran,while close to stem under the high-speed condition. From tlae research on trimaran roiling performance influenced by the hull roll radius, it is shown that the smaller of roll radius, the better of roll stability.
