Rolling Control Analysis of Baohua Ro-Ro Ship

A three dimensional solid model of Baohua ro-ro ship in Bohai Bay is built using three dimensional modeling software. The model is then imported into Adina finite element analysis software. In this way, the problem that the finite element model can not approach the actual profile of the ships is solved satisfactory. The modal analysis of the ro-ro ship in Bohai Bay was performed in this paper using Adina finite element analysis software. The rolling modes and the modal frequencies are obtained by the analysis. The cargoes on the ro-ro ship were used for construction of the anti-rolling device to control the rolling movement of the ship. The simulation results indicated that good rolling control effects have been achieved.
