Abstract

The submarine whip motion induced under underwater blast load is very serious to its destructive impact and threatens the survival condition of the submarine. Therefore, the whip dynamic response of cylindrical shell structure under the underwater blast load is experimentally investigated. First, the type of submarine transverse bulkhead is selected as the experimental object. Next, strain gauges are selected as the measurement sensors for the experiments, for a total of 14 evenly distributed measurement points for data acquisition and measurement of the strain response of the reinforced cylindrical shell under the underwater blast load. Ultimately, the variation pattern of strain values with time generated strain at each point location is derived, and the location of the most vulnerable cylindrical shell structure is obtained.
