| Abstract: | 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. |
