ANALYSIS OF SINGLE-AXIS GYROSTABILIZER ON A SCALED-SIMPLIFIED-HULL MODEL FOR STABILIZATION

Abstract

Advancements in technology have led to the development of new mechanisms and systems for stabilizing marine vessels, with a focus on enhancing safety and stability to prevent capsizing incidents. Roll motion has been a critical factor in ship stability, as excessive rolling can lead to crew discomfort, decreased efficiency, and even capsizing. This paper outlines the development of Gyrostabilizer on a 3D-Printed Body of a Simplified Hull-Model based on Ground Testing that focusses on the hull’s stabilization in rolling motion only. Gyrostabilizer design in the system is mainly to show how the difference in passive and active control of gyrostabilizer affects the efficiency of rolling reduction of the scaled-hull model as compared to when it is naturally rolled. This experiment's analysis is based on the goal of achieving the stability in static model of rolling motion, and discussions related to it are included in the paper. The method used in this research is force excitation from a side of the mechanism and force-pushing slider on the system. The research results encompass the gyro system with a passive and active control in providing a better roll reduction with the same amount of force excited from a side on the system. Averaging from all three tests for each control, a percentage of roll reduction of 14.81% and 33.93% was achieved when implementing passive and active control respectively.
