摘　　要：为探究船舶参数横摇发生条件,以一艘汽车运输滚装船为研究对象,采用计算流体力学(CFD)软件STAR-CCM+建立虚拟水池并进行数值模拟。通过模拟静水中船舶横摇自由衰减,计算出船舶的横摇固有周期;采用控制变量法分别探究波高、波长、航速和遭遇频率等对船舶参数横摇的影响;为该船设计并搭载减摇水舱,分析减摇水舱对参数横摇的抑制效果。结果表明:在迎浪规则波中,当波浪达到一定高度,且波浪遭遇频率为船舶横摇固有频率的2倍时,该船的参数横摇最为剧烈;当减摇水舱固有周期等于该船的横摇固有周期时,减摇水舱对参数横摇现象有较好的抑制效果。In order to explore the conditions of parametric rolling of ship,a vehicle transport ro-ro ship is taken as the research object,computational fluid dynamics(CFD)software STAR-CCM+is used to establish a virtual pool and perform numerical simulation.By simulating the free attenuation of ship roll in still water,the natural roll period of ship is calculated.The influence of wave height,wavelength,speed and encounter frequency on ship parameter roll is studied by using control variable method.The anti-roll tank is designed and carried on the ship,and the effect of anti-roll tank on parametric roll is analyzed.The results show that,when the wave reaches a certain height and the frequency of wave encounter is twice than the natural frequency of ship roll,the ship parameter roll is the most intense.When the natural period of the damping tank is equal to the natural period of the ship roll,the damping tank has a good suppression effect on the parametric roll phenomenon.
