英文摘要: Abstract(#br)For the motion prediction of a trimaran, the hydrodynamic interference between main hull and outriggers is a significant factor and need to be taken into consideration. The high-speed slender body potential flow theory (2.5D method) is a high-efficient method to predict the seakeeping performance of ships in waves and has been validated for mono-hull ships. In this paper, the 2.5D method has been applied to predict the vertical motion (heave and pitch) and added resistance of a trimaran in head-sea waves. In addition, a trimaran model test was carried out to analyses the relationship between the travelling speed, outrigger layout, incident waves and heave, pitch amplitude, added resistance of a trimaran. The experimental results are also compared with the numerical results in...
