【摘要】 从受力分析出发 ,做了 5种小水线面双体船约束模型水动力试验 ,并与拖曳船模试验结果作比较 ,两者之间有较好的一致性 .根据试验结果 ,分析了在约束情况下的小水线面双体船的水动力特性 ,认为约束船模试验是以船舶水动力特点去研究中低速下小水线面双体船的航行姿态和稳定性能的一种有效手段 .并可为小水线面双体船的 3维流体力学理论计算、性能预报模型提供验证、修正基础依据 .更多还原

【Abstract】 Five SWATH restrained models were tested to analyse the ship’s posture in speeding by force analyzing, and compared with the towing model test. The results are corresponded well especially at the middle and low speed (Fr<0.48). It is proved that the restrained model test is an effective means based on force analysis to study SWATH’s posture and stability in voyage. The work can provide a checking and perfecting base for SWATH’s 3D model hydrodynamic calculation research.更多还原
