Numerical Computation of Sloshing-Induced Force in Complex Ship Tanks under the Excitation of Ship Rolling Motion Based on the MPS Method

Liquid sloshing in ship tanks would have a direct effect on dynamic stability, and thus is of great importance for navigation safety. To calculate the sloshing-induced force real tanks, this paper presents an approach to numerically simulate liquid-sloshing complex using moving particle semi-implicit (MPS) method. The calculated used investigate different excitation conditions which realistic motions under loading been taken into account. Simulation results show that maximum much bigger than corresponding static one. Meanwhile, both rolling angle period significant effects liquid sloshing.
