Abstract

Liquidjetsformedwhenbubblescausedbyunderwaterexplosioncollapsecouldseriously threatenthelocalstrengthofwarships.Inordertostudythedamageeffectofvesselstructuresubjectedtobubblejet, aseriesofunderwaterexplosiontrialswereperformedbyusingatypicalcabinmodel. Waterpressure,bubblepulsatingcycle,thedynamicstrainandplasticdeformationofoutplates wereobtained.Dynamicalresponsesofcabinstructurewithvariousimpulsivefactorswereanalyzed, waterpressurewasmeasured,theoccurrenceofbubblejetwasthendiscussed.Damageeffectandinfluencerangeofoutplatescausedbybubblejetwereinvestigated. Theresultsshowedthatcompared withshockwaveload,thejetimpactcouldconcentratebubbleenergyandcauseseriousdamagetolocalstructureofwarships. Undercertaincircumstance,thedamageeffectcausedbybubblejetwould bemoreseriousthanthatcausedbyshockwaveloading.Therefore,intheresearchonproximityunderwaterexplosion, inadditiontotheshockwaveloading,thebubbleloadingcouldnotbeneglected.
