前三体船概念及其阻力和运动性能试验研究

摘要

The resistance and motion characteristics of trimaran hull form have been studied by experimental method.The model experiment consists of two parts: the resistance experiment on calm water and the motion experiment in regular waves.According to the experimental data, it can be found that the longitudinal arrangement of the side-hulls plays an important role in trimaran resistance and motion characteristics.For high speed range, the trimaran resistance and motion performance could be significantly improved by placing the side-hulls before the mid-ship of the main hull.Based on the experimental results, a new ship type known as fore-body trimaran is presented.%采用模型试验方法研究了三体船侧体的纵向位置变化对三体船阻力性能和运动性能的影响.模型试验包括三体船在静水中的阻力试验和在规则波中的运动试验两部分.实验结果表明,三体船侧体的纵向位置对三体船阻力和运动性能的影响显著;在高航速段,将侧体的纵向位置选取在主体舯前位置,能明显改善三体船的阻力件能和运动性能.基于此.提出前三体船的概念.
