摘　　要：应用船舶水动力学理论,建立了有限水深薄船引起水底压力变化的数学模型,编制了船舶水压场预报软件。该软件可根据给定的水深、航速和船型参数,快速计算并直观地显示出水压场曲线。将典型船舶水底压力场的计算结果和实验结果进行了对比,结果发现二者具有较好的一致性,表明该软件具有良好的预报能力。该软件可用于水压引信负压延时组合设计,对于水压引信的设计和船舶自身防护也具有一定的应用价值。Based on the ship hydrodynamic theory, a mathematical model of bottom pressure variation induced by a moving thin ship in finite depth is constructed, and a software to forecast ship hydrody- namic pressure field （SHPF） is developed. The pressure field can be simulated quickly and its curve can be shown directly by the given water depth, speed of ship and parameters of ship form. A good a- greement exists between calculated and experimental results of the ship hydrodynamic pressure field. The software can be used to design the hydrodynamic pressure fuse in the combination of negative pressure with its duration time. The software is useful for the pressure fuse design and ship＇s own defense.
