摘要
针对水下航行体近海底和近水面运动的不同特点 ,应用船舶水动力学理论 ,建立了细长体和回转体引起海底压力变化的数学模型 ,并对典型艇体的海底压力场进行了计算 ;研制了高精度的水底动压测量系统 ,理论计算和实验结果具有较好的一致性 .研究表明 ,水下航行体的压力场特征明显 。
To counter different features a underwater vehicle was moving above sea bottom or beneath water surface, mathematical models of pressure variation above sea bottom caused by a slender body or a revolutionary body were established, and the pressure field of typical submarine body was calculated. A high accurate system for measuring hydrodynamic pressure variation was developed, a good agreement between computations and measurements was achieved. The research results appeared that the pressure characteristic of underwater vehicle was apparent, which can be used to detect and recognize objectives moving beneath water susface.
