摘　　要：基于查德惠克被动式减摇水舱理论,分别建立了单侧气阀和两侧气阀控制的可控被动式减摇水舱系统数学模型.推导了最佳相位关系和气阀控制规律的理论依据,对不规则波作用下的可控被动式减摇水舱系统进行了仿真研究.仿真结果表明,水舱内水的流动与船舶横摇运动基本符合最佳相位关系,气阀控制规律是可行的.通过对单侧或者两侧气阀进行控制,都能够使水舱内水流的振荡周期及时地适应变化的横摇周期,两侧气阀控制的减摇效果要优于单侧气阀控制.Mathematical models of passively controlled anti roiling tank are developed by adopting two side valves control and one side valve control respectively. Optimal phase relation and air valve control rule are derived. Simulation results in irregular waves show that the optimal control phase relation is satisfied between water flow and roll motion, and the air valve control rule is effective. The oscillation period of passively controlled anti rolling tank can keep up with the rolling period in time by controlling two side air valves or one side air valve. The control of two side air valves is better than one side air valve in stabilization effects.
