摘　　要：为探讨在高速三体船上采用多种附体同时实现减阻和减摇的方法,论文首先对三体船裸船体在静水和迎浪规则波中的受力、姿态和运动进行了数值计算和模型试验,两者吻合较好。随后在三体船上增加球鼻艏进行数值计算,结果显示所采用的球鼻艏可以减小三体船的静水阻力系数,且对航态影响不大。之后,对同时对安装球鼻艏和T型翼进行数值计算,计算发现,与裸船体相比,带有球鼻艏和T型翼的三体船能够得到在阻力系数有一定减小的情况下实现纵摇的显著改善。In order to reduce resistance and pitch motion of a trimaran with multi-appendages,the force acting on the hull without appendage,its gesture,and motion in regular head waves is calculated and compared with experimental data,and good agreement is shown.Then,a bulbous bow is added on the trimaran,the numerical result suggests that the resistance in calm water can be reduced by the bulbous bow,while the gesture is not influenced remarkably.At last,numerical simulation of the trimaran with a bulbous bow and T-foil is performed,and the result suggests that the calm water resistance and pitch motion can be reduced simultaneously by appendages.
