摘要
本文通过船模试验探讨了一艘千吨级江海联运船的浅水效应,得到了浅水中有效马力增加、推进效率降低和船舶产生下沉和纵倾的一些规律,还用理论方法估算了该船在海浪中的各种耐波性指标,得出螺旋桨出水次数多是此类船型存在的突出问题,并从设计角度提出了改进措施。
In this paper, model experiments in shallow water were carried out for a 1000 DWT class river and sea through ship. Fffective power, propulsive efficiency, sinkage and trim of this type of ship in shallow water were measured. A number of seakeeping indexes of the ship were calculated by theoretical method. It is found that propeller blades seriously emerge out of the water for ultra-shallow draft ship travelling in waves. In order to improve the ship performance characteristics some suggestions are made.
