[ABSTRACT]In order to optimize the structural parametersof conical shaped charge and explore the conditions for achieving disintegrationwithout detonation of shelled Composition B，the jetformation process wassimulatedusing AUTODYN softwarebased onorthogonal experimental method.The influences of diferent charge structural parameters such as cone angle，material，wall thickness，and charge diameter on the jet detonation capability v2d were studied. And the structural parametersfor penetrating shelled Composition Bwereoptimized.Simulationof penetrationofsteelshelled CompositionB with projectiles was conducted using theselected charge structure.The efectsof explosion height and shell thickness on the response state of explosives were investigated.The mechanism of jetpenetrationand detonationof shell chargesatdiferent explosionheightswasalsoanalyzed.Finaly，experimentalresearch wasconductedtoverifythesimulationresultsof the response stateof explosives.It was foundthat，forthe selected shellsteel shelland20mm caliber energy gathering charge，when the explosion height is less than 3.50d （shell thickness of 0.2d ）or d （shell thickness of 0.3d ）， CompositonBdetonatesunder theactionof theshock waves directly generated byjetpenetrationorthereflectedwaves obtained from shock wave contact with the back plate.When the explosion height is greater than 5.00d （shell thickness of 0.2d ）or 2，05d （shell thickness of 0.3d ），the shock wave and reflected wave generated by the residual energy of the jet could notcausethe detonationof Compositon B，and disintegrationwithoutdetonationof theammunitioncouldbeachieved.
