摘要
应用势流理论求解水动力系数,采用STF二维切片理论预报带T型翼和尾压浪板的高速穿浪双体船的纵向运动耐波性,目前大多数以定常翼理论处理T型翼和尾压浪板,高航速下升沉和纵摇峰值预报结果较实验结果偏大。为改善高速穿浪双体船耐波性预报,将Theodorsen振动翼理论应用到穿浪双体船耐波性预报中,较好地解决了预报结果偏大问题,并对T型翼和尾压浪板减摇机理进行了阐述,垂荡峰值的预报误差较小,可达1.29%,纵摇峰值误差可达1.41%。
The potential flow theory is used to solve the hydrodynamic coefficients. By using STF 2D strip theory, lon-gitudinal motion Seakeeping of High-speed Wave-piercing Catamaran（WPC） with T-foil and flap is predicted. The calcu-lation of T-foil and flap is mostly based on steady wing theory at present, however, the peak value error of heave and pitch at high speed between the numerical calculation and experiment is too large. To improve the seakeeping prediction of High-speed Wave-piercing Catamaran, Theodorsen vibration wing theory is firstly applied to WPC seakeeping prediction and a satisfactory result is got. The mechanism of reducing heave and pitch is expounded. The prediction error of heave is satisfactory by 1.29%, and the pitch one is satisfactory by 1.41%.
