横荡对被动式减摇水舱运动的影响研究

Influence of Sway Motion on Passive Anti-rolling Tank

被动式减摇水舱是减少船舶摇摆的重要装置之一 ,目前对它的研究大多数都只针对单纯横摇运动。而本文在考虑了横荡对水舱运动的影响后 ,基于U型被动式减摇水舱理论推导了耦合横荡的“船舶 -水舱”系统的数学模型 ,并通过仿真和试验研究证实了考虑横荡对水舱的影响是很必要的 ,更符合于实际情况。

The passive anti-rolling tank is one of important ship stabilizers widely used today.But at present,research on the tank is mostly aimed at its rolling movement.In this paper,emphasized on considering the influence of sway motion on the passive anti-rolling tank,a mathematical model of “ship-tank” system coupled with sway motion is developed based on the U-shaped passive anti-rolling tank theory.Both simulation results and experimental data indicate that it is necessary to consider the influence of sway motion on the anti-rolling tank,which is more agreeable to the actual circumstance.
