The bubble load caused by underwater explosion is the main reason for the overall damage of ship structure.Studying the dynamic characteristics of underwater explosion bubbles is crucial to the research of underwater weapon development and ship protection.Starting from the loading characteristics bubble pulsation in underwater explosion,the research progress of bubble dynamics theory,experiment and numerical simulation is reviewed.Meanwhile,the typical research results of the bubble non-spherical collapse process,bubble coupling with different structural surfaces and multi-bubble coupling in free field and the fragmentation of multiple bubbles in water after interaction are summarized.On the basis of the existing research results,it is suggested that the bubble motion mechanics model should be established considering the factors inside the bubble and different environmental factors in water,a more systematic experimental study should be carried out on the movement characteristics of bubbles in non-ideal explosive water,the research of multi-bubble coupling process under near-boundary conditions should be further strengthened.
