Theoretical and Numerical Analysis of Sloshing Effect on Ballast Submarine

This study considers the analytic model for submarine. The Submarine was considered to be rigid body supported by non-permanent pole with distributed spring damper. The use of the floating body mechanisms equation is the development of the equation of force and the basic moment to obtain the pattern of submarine movement due to ballast. the development of this equation to illustrate the model performed through experiments and numerical simulations. equations of this model of analysis is one method that is quite simple, so that researchers can know earlier than the pattern of submarine motion that will be analyzed. From the results of the study, it was found that the submarine ballast has increased the effect on submarine stability that is reducing the submarine's stability.
