为了研究附体对潜艇阻力性能的影响，对7种不同附体布置的SUBOFF潜艇模型进行直航运动的数值仿真，对各潜艇模型的摩擦阻力、粘压阻力和总阻力进行预报。通过数值仿真发现，附体的布置使粘压阻力显著增加。分析潜艇表面压力分布情况和潜艇周围速度场特性，对减少潜艇阻力、提高潜艇快速性和提高潜艇战斗力有重要意义，也为潜艇的初步设计和附体优化提供了参考。
In order to study the influence of the appendages on the resistance of the submarine, the numerical simulation of the direct motion of the SUBOFF submarine model with different appendages was carried out. The frictional resistance, the cohesive resistance and the total resistance of each submarine model were predicted. It is found that the arrange of the appendage makes the viscosity resistance increase significantly. The pressure distribution on the submarine surface and the velocity field characteristics around the submarine are analyzed. It is of great significance to reduce the resistance of the submarine, improve its rapidity and combat effectiveness, and provide a reference for the preliminary design of the submarine and the optimization of its appendages.
