摘　　要：水下航行体引起的水底压力变化是航行体的重要目标特性之一,可用于水下运动目标探测和水中兵器研制.基于船舶水动力学势流理论,建立了水下航行体水底压力计算模型.利用HessSmith方法,对大深度水下航行体的压力场分布进行了计算,分析了航行体水压场沿纵向和潜深的变化规律,计算结果和实验结果有较好的一致性.The pressure variation on sea bottom caused by underwater vehicle was an important objective characteristic,which can be used to detect objectives moving beneath water susface and develop undersea weapons.A mathematics model of hydrodynamic pressure on sea bottom of underwater vehicle was established base on potential flow theory of marine hydrodynamics.The pressure field of underwater vehicle deep in sea was calculated by Hess-Smith method,and the law of pressure field vary with longitude and depth was analysed,a good agreement exists between computations and measurements.
