摘　　要：舰船航行时在其下方附近产生水压场。这种水压场无法消除 ,也极难人工模拟。水压水雷就是根据航行舰船的水压场特性而引爆的。从舰船的安全防护角度考虑 ,可在船体底部加装某种附体 ,使舰船原有水压场发生改变 ,从而避免引爆水压水雷。对在船底加装翼板、回转体等附体所造成的舰船水压场畸变进行了试验研究和数值计算。在拖曳水池中进行了船模水压场测量 ,比较了加装附体前后舰船水压场的特性 ,据此分析了采用舰船水压场畸变方法防御水压水雷的可行性。比较了加装翼板和回转体的防水压水雷效果。The hull movement through the water will cause pressure distortion around the ship. To protect ships from mines armed with pressure sensitive fuses, bodies in certain forms can be fixed under the ship, which may superimpose additional pressure upon the normal water pressure field. The effect of the body form and position on the additional pressure is investigated in this paper. A series of model tests were performed in a towing tank to measure the water pressure, which is compared with the numerical results and good agreement is obtained. It is shown that the hydroflap is better than the revolutional body when it is fixed on ship bottom to change the water pressure field. It is feasible to protect a ship from pressure sensitive mines by using hydroflaps.
