Whipping response analysis for a naval surface ship caused by UNDEX(UNDerwater EXplosion) bubble pulse should be carried out for the evaluation of longitudinal hull-girder strength. For this evaluation, 1-D beam analogy analysis and 3-D analysis using the finite element method are typically used during the ship design process. But these analytic calculation processes are very complicated in order to compare and estimate the calculated UNDEX whipping moments with the allowable bending moment of a given design which can be derived from the allowable strength criteria of longitudinal hull girder structural members.
In this paper, to decrease these complicated flipping analysis process and promote the calculation efficiency, an integated whipping analysis program has been developed based on the thin-walled Timoshenko beam theory and the modal analysis method using wetted1 vertical vibratory modes of the hull-girder. This program is developed for the efficiency of UNDEX whipping analysis process based on best practices including to effectively manage, utilize and evaluate the massive and various simulation data and results including UNDEX scenarios and ship design data. Finally, the usefulness of the developed program has been confirmed with the comparison of results obtained by between 1-D and 3-D analysis.
