Design and Simulation Research of Leveling Tanks System

Abstract

This paper introduced a leveling tanks system of the ship based on Visual C++. The simulation system is consisted of a leveling tank, a leveling system controller and a ship motion simulator three parts. This paper focuses on the system leveling effect, when the roll is generated by steering as well as loading and wave interference under conditions of direct of the ship. In the research of the ship rolling, which is generated by steering, tanks model combining of traditional four degrees of freedom, getting a new four degrees of freedom "Ship-Tank" movement mathematical model. We calculate the motion state of the ship, and output multiple parameter information of ship motion based on the mathematical model, and then level the roll motion generated by ship steering using control strategies. Simulation results show that, in the conditions of both direct and steering, the system is able to achieve the desired effect of leveling, and thereby it provides reliable basics for designing and researching of leveling tanks.
