摘　　要：基于有限元方法,通过仿真计算,比较了三种不同主体尺度下三体船的垂荡、纵摇、横摇运动响应算子。因不同的航行速度对运动算子有一定影响,故分别在低航速和高航速下进行比较。通过不同航速下的垂荡、纵摇、横摇性能对比,得出主体狭长型三体船运动响应性能均最佳,最适合作为三体船主体的尺度。Based on finite element method ,this paper compares the heave ,pitch and roll response operator for three different trimarans with different main dimensions by numerical simulation. The comparison is conducted under low speed and high speed, respectively, because the sailing speed will impact on the response operator differently. It is concluded that the motion response of a trimaran with narrow main body is optimal by comparison of heave, pitch and roll performance under different speeds,which is best to be taken as the main dimensions for a trimaran.
