Abstract

Aseriesofexperimentswereconductedtoinvestigatethesynchronyofthemulti-pointring initiatorappliedtoashapedchargeandthepenetrationcapabilityoftheshapedchargeswiththemultipointringinitiatorsintoreinforcedconcr tetargets.Theoutputsynchronyofallpointsofthemultipointringinitiatorwasmeasuredbyusingthehigh- speedphotographyandfiberprobetechnique.Itis showedthattheoutputsynchronyofallpointsisgoodandthelongesttimedifferenceislessthan 0.1s.Theshapedchargeswereinitiatedtopenetrateintoreinforcedconcretetargetsbyapplyingthe multi-pointringinitiatorsandthecentralpointinitiation,respectively.Comparisonoftheexperimentalresultsshowsthatthemulti- pointringinitiatorscanimprovemarkedlythepenetrationcapability oftheshapedcharges.
