Influence of sway motion on passive anti-rolling tank

Abstract

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