Large-scale underwater high-pressure bubble movements form a strong pulsating load and have a coupling effect with nearby structures.Under the action of underwater bubble loading, slender body structure such as hull will generate whipping response and endanger its total strength.In this paper, Wilkinson spherical bubble model and hull girder model are used to establish the whipping response calculation method for slender body structure under the action of underwater bubble pulsation load. The calculation process is greatly simplified, and the method is verified by three-dimensional finite element method.The results show that the bubble pulsation frequency has a coupling relationship with the natural frequency of the hull girder.
