It was inevitable that submarine will be attacked by underwater weapons such as torpedo,mine,guided missile and the depth water bomb etc in the sea warfare,therefore the question of submarine anti-explosion shock was got continuously attention.At the same time,improving submarine anti-explosion shock ability is a important aspect for enhancing submarine vitality effectiveness.In this paper,we proposed three new research methods based on the research status about submarine anti-explosion shock and some common methods,and the point analyzes is the bubble curtain reduce to underwater blast wave at the theories mechanism and experiments,provided an effective research method for the submarine anti-explosion shock defense research.
