Abstract

Theemulsionexplosiveswerechargedintothecurvedgroovemachinedonanironplate. Thedetonationvelocitiesoftheemulsionexplosivesweremeasuredbyusingtheshortingpinsinthe casesofdifferentchargecross-sectionalareasanddifferentchargecurvatures.Andtheinfluencesof thechargediametersandthechargecurvaturesonthedetonationpropagationvelocitiesintheemulsionexplosiveswereanalyzed. Itisshownthatthedetonationvelocitiesdecreaselinearlywiththedecreasingofthechargecurvatureradiiandthechargediametersquare. Whenthechargediameteror thecurvatureradiusreducesbelowacertaincriticalvalue,thedetonationreactionceases.Basedon theexperimentaldata,anempiricalformulawasproposedforcalculatingthedetonationvelocityofthe emulsionexplosivesintheconditionthatthecurvatureradiusandthechargediameterweregiven.
