摘要
液舱内自由液面的晃荡会影响船舶的稳定性。通过引入实用稳定性的概念,研究了在晃荡影响下的潜艇运动实用稳定性。利用计算流体力学软件对潜艇横摇过程中液舱的液面晃荡进行了模拟计算,根据仿真结果,分析了液舱晃荡对潜艇稳定性的影响,建立了液舱晃荡和潜艇横摇运动的耦合作用模型。通过数值仿真,验证了在液舱晃荡影响下的潜艇横摇运动系统的实用稳定性,从而证明了该方法的可行性。
The tank sloshing can have an enormous impact on the ship and may cause the instability of ship motion.The practical stability of the submarine motion under the sloshing impact was studied.Numerical simulations of sloshing in the submarine tank were performed using the commercial computational fluid dynamics code.The coupling effects of tank sloshing and submarine motion were analyzed based on the results of the simulations,and the model of the submarine roll motion under sloshing impact was constructed.The practical stability of a typical submarine roll motion system was analyzed based on a numerical simulation.Therefore,the feasibility of the approach was verified.
