摘　　要：在海流作用下多台潜水器进行协同作业时,潜水器之间会产生相互干扰的水动力,进而影响潜水器的作业姿态。针对此问题,本文采用RANSE方法求解N-S方程,对两台潜水器在相向运动时不同间距下的水动力变化进行了研究;在此基础上,对两台潜水器悬停作业时,不同横向海流作用下潜水器间的干扰水动力对潜水器作业姿态的影响进行了仿真。结果表明,在作业工况下,潜水器间的干扰水动力主要影响潜水器的俯仰角,并且随着海流速度增大,对俯仰角的影响越大。When underwater vehicles cooperate in a deep-sea operation,there are interference forces be⁃tween the underwater vehicles under ocean currents,and the forces between the underwater vehicles will have an impact on the posture of the underwater vehicles.In this paper,the RANSE method is used to solve the turbulence equation,and the hydrodynamic interference of two submersibles at different intervals during movement in opposite directions is studied.Moreover,when the two submersibles are in a hovering state,the influence of the hydrodynamics between the submersibles interference on the submersible posture under dif⁃ferent lateral currents is simulated.The results show that the hydrodynamic interference between submers⁃ibles mainly affects the pitch angle,and that,with the increase of the current velocity,the influence on the pitch angle increases.
