摘　　要：为研究外部搭载装置对潜艇操纵性的影响,采用RANS(Reynolds-averaged Navier-Stokes)方法对搭载某水下航行器的SUBOFF潜艇约束模运动进行数值模拟。基于获得的水动力导数,评估外部搭载对潜艇动态稳定性与机动性的影响。首先,对SUBOFF斜航运动水动力参数计算结果进行网格收敛性分析,并将数值结果与试验数据对比,验证数值方法的可靠性。其次,数值预报搭载状态下的SUBOFF潜艇在垂直面与水平面上典型的静态和动态约束模运动的水动力和力矩,并通过拟合曲线求取相应的水动力导数。在此基础上,用操纵性衡准数评估潜艇稳定性与机动性。结果显示,未搭载与搭载状态下的SUBOFF潜艇均不具有稳定性,且在搭载状态下其稳定性会进一步降低;外载装置能改善潜艇垂直面的应舵性和水平面上的回转性。To investigate the maneuverability of a submarine influenced by its external carrying vehicle,the Reynolds-averaged Navier-Stokes method is applied to simulate captive motions of a SUBOFF submarine model carrying with an underwater vehicle.Based on the predicted hydrodynamic derivatives,the dynamic stability and the steerability of the submarine under the influence of the external vehicle are evaluated.The mesh convergence analysis of the simulation for the SUBOFF oblique motion was conducted,and the reliability of the numerical method was verified by comparing the numerical results with experimental data.Numerical simulations of captive motions in vertical and horizontal planes for the SUBOFF with the external vehicle are conducted,and the hydrodynamic derivatives are determined by curve fitting.Based on the predicted hydrodynamic derivatives,the dynamic stability and steerability of the submarine are evaluated using the corresponding maneuverability criterion indices.The results indicate that in both cases without and with an external carrying vehicle,the SUBOFF lacks dynamic stability,while the external vehicle will further reduce its stability.However,the external carrying vehicle can improve the course-changing ability of the submarine in the vertical plane and the turning ability in the horizontal plane.
