摘　　要：针对潜艇水下航行时的压力场特性,应用船舶水动力学势流理论,建立计算潜艇水压场的数学模型。采用Hess-Smith方法将面源分布于艇体表面,对潜艇引起的水底压力变化进行数值计算,并与主艇体及已有实验结果进行比较。分析潜艇水压场的分布特点以及水深、指挥台围壳对压力场分布的影响。理论计算与实验结果对比表明,二者之间吻合良好。To counter the pressure field characteristics of a underwater submarine, a mathematical model of submarine hydrodynamic pressure field was established based on marine hydrodynamic potential flow theory. The sources were distributed on the submarine hull surface by the Hess-Smith method. The pressure caused by submarine in finite water depth was calculated and compared with main body of submarine and experimental results. The character of submarine hydrodynamic pressure field and the effect of water depth and sail appendage on the pressure field were analyzed. A good agreement is achieved between theoretical calculation and experimental results.
