Abstract

Akindofdoubleconelinerwasdesigned,itsformationandpenetrationmechanismswere studiedbymeansofnumericalsimulationsandexperiments,thejetparametersofthelinerswithdifferentstructureswereanalyzedtoacquiretheoptimizedresultthroughtheorthogonaldesignmethod, andthepenetrationcapabilitiesoftheoptimizedlinerswereexploredbynumericalsimulationandexperimentalmethods. Resultsdisplaythatthelinercanform ashapedchargejet,anexplosively formedprojectileandaslug.Thesmallconeangle2canexerciseasignificantinfluenceonthehead velocityofthejet,andthelinerthicknesstandthelargeconeangle2canobviouslyaffecttheprojectilevelocity. Fortheoptimizedparametersoft=0.14cm,2=50,2=135andN=0.4or0.5, theheadvelocitiesofthejetscanreach6613and6839m/s,respectively;thevelocitiesoftheprojectilescanreach2247and2095m/ s,respectively;thepenetrationdepthscanreach8.24and8.31cm, respectively;andtheholesizescanreach2.12and2.08cm,respectively.Sothedesignedbiconical linerstructureisreasonable,bywhichcanensurethevelocityoftheshapedchargejetandgreatlyimprovethevelocityoftheexplosivelyformedprojectile.
