摘　　要：使用两个具有不同固有频率的被动式U型减摇水舱能给横稳心高变化范围很宽的船舶提供很好的减摇效果。本文给出了参数频率响应法,推导了装备两个具有不同固有频率的被动式U型减摇水舱的船舶横摇频率响应函数,分析了影响船舶横摇频率响应幅值的水舱参数,通过仿真详细研究了水舱参数对船舶横摇减摇的影响。研究结果对于双被动式U型减摇水舱的设计具有重要的指导作用。To use two passive U-tube anti-rolling tanks with different natural frequencies can provide very good rolling reduction over a wide range of metacentric height of ship.This paper introduced the parameter frequency response method,developed ship rolling frequency response function equipped with two U-tube anti-rolling tanks with different natural frequencies,analyzed the tank parameters relative to rolling frequency response amplitude,and researched the effect of tank parameters on the ship rolling amplitude in detail,which would play an important guide role in the design of two tanks system.
