摘要
舰船水压场的研究是设计新型水压水雷、研制水压扫雷具以及舰船自身防护的依据,具有重要的军事意义。基于船舶水动力学势流理论,建立了计算有限水深舰船水压场的数学模型。采用Hess-Smith方法将面源分布于船体表面,对舰船在有限水深引起的水底压力变化进行了数值计算,并与已有的实验结果进行了比较。进一步分析了舰船水压场的分布特点和水深、船体外形对压力场分布的影响。理论计算与实验结果对比表明:两者之间吻合良好。
The research on the hydrodynamic pressure field of a ship is the foundation of designing a new pressure mine,developing a minesweeper and protecting the ship,which is of great military significance.A mathematical model for the ship hydrodynamic pressure field was established based on the marine hydrodynamic potential flow theory.The sources were distributed on the ship hull surface by using the Hess-Smith method.The pressure caused by the ship at the limited water depth was calculated and compared with the experimental results.The characters of the ship hydrodynamic pressure field and the effect of water depth and the ship hull shapes on the pressure field were analyzed.The comparison shows that a good agreement is achieved between the theoretical calculation results and the experimental ones.
