摘　　要：减摇水舱在船上的布置位置对减摇效果影响较大,特别在垂直方向的布置对减摇效果有很大的影响.本文基于"船舶—水舱"系统的运动微分方程,详细分析了减摇水舱在船上垂直方向布置对船舶横摇模型质量惯性矩、横摇复原系数、横摇固有频率、船舶横摇运动和舱内液体运动的影响.通过对给定船舶减摇水舱的实例分析,指出了除水舱固有频率和阻尼外,垂直方向布置也是影响水舱减摇性能的主要因素之一,并给出了最佳减摇时水舱垂直布置的条件.Installed location of anti_roll tank on ship will affect roll reducing effect,especially the vertical installed location has much influence on roll reducing effect.In this paper,based on the differential equation for the motion of the anti_roll tank wihtin the ship on the rolling inertia moment,rolling righting moment coefficient,rolling natural frequency of the ship,ship rolling motion and the motion of water in the tank.An example of the given ship proved the correctnes of the analysis.It indicates that in addition to natural frequency and damp of tank,vertical location of the tank within the ship is also one of main factors influencing on the stabilizing effect of the tank.The location of tank with best stabilizing effectivenes is given.
