摘　　要：为研究三体船适配T型水翼的减摇效果,建立T型翼-三体船系统的运动方程。从T型翼的水动力特性入手,分析T型翼对三体船的作用,推导出T型翼对运动方程中水动力系数的贡献,并针对某三体巡视舰及其适配T型翼进行了仿真运算。结果表明,T型翼可使该船垂荡运动响应极值降低40%左右,纵摇运动响应极值降低45%左右。A motion formula based on a T foil-trimaran system is built to research the anti-rolling effect of the trimaran fitted T foil.Started with the hydrodynamic characteristic of the T foil,the impact of the T foil on the trimaran was analyzed,the contribution of the T foil to the hydrodynamic coefficient in the motion formula was deduced,and a simulation computation of a trimaran patrol ship and its T foil was conducted.The result shows that the T foil could cut down about 40% of the heave motion response extremum,and could give a 45% reduction of pitch motion response extremum.
