摘　　要：潜艇航行引起的流场压强变化称为潜艇水压场,其特性常被应用于水雷,以实现目标探测,攻守兼备。考虑指挥台围壳、尾翼影响,以全附体艇体为研究对象,在验证性研究的基础上,基于粘流理论研究了潜艇水压场特性,揭示了附体对艇体表面、周围流场、水底流场的压强分布影响规律。结果表明:附体对艇体表面的压强分布影响显著,但影响范围局限于附体小区域,而对水底处的水压场影响仅在潜艇近底航行时才略显著,可见非近底航行工况下可忽略附体影响,实现潜艇水压场的快速预报;在研究近水面航行工况时,水面兴波对海底潜艇水压场的分布存在影响,具体影响潜艇水压场的峰值大小和位置等。The pressure change of flow field caused by submarine navigation is known as submarine hydrodynamic pressure field,which is often used in mines for target detection so as to achieve both offensive and defensive effect.Considering the influence of the command deck enclosure and stern,the fully appended hull was used as the research object.Based on the validation study and the viscous flow theory,the submarine hydrodynamic pressure field was studied,whereby the effect of the appendage on the pressure distribution on the surface of the hull,around fluid and on the bottom were further revealed.The results show that the influence of the appendage on the pressure distribution on the surface of the hull was significant,but it was limited to a small area of the appendage,while the in-fluence on the hydrodynamic pressure field at the bottom was significant when the submarine was sai-ling near the bottom,and thus,the influence of the appendage can be ignored under the non-bottom sailing conditions for fast and efficient forecasting.Moreover,with the study of near-surface navigation condition,the influence of surface waves on the distribution of submarine hydrodynamic pressure field exists,which affects the magnitude and the position of pressure peak.
