[ABSTRACT]Anew method for testingthe impact resistance peiformance digital electronic detonators based on the split Hopkinson pressure bar （SHPB）impact system was proposed to address the problems cumbersome operation and difcult quantitativeassessment digital electronicdetonators.Thedamage characteristics digital lectronicdetonators under diferent impact strengths were studied using SHPB impact system and underwater explosion impact system.A mathematicalmodel wasestablishedfor theenergyloss digital electronicdetonators underimpactloadloading.Theequivalence the mechanical environment providedbythetwo experimental methods was comparedand analyzed.Theresults ndicate thatunder themechanical loadprovided bythetwo experimentalmethods，digital electronicdetonatorsexhibitthesame damagecharacteristics.The mainreason for the failure digital electronicdetonatorsunder impactloads is theloss capacitorignitionenergy，and thelosscapacitorignitionenergyis positivelycorelated with impactstrength．The SHPB shock systemcaneffectivelysimulate the situation wheredigital electronic detonatorsaresubjected toshock waves.Itcan comprehensively evaluate the impact resistance performances industrial electronic detonators.

数码电子雷管是一种应用微电子技术、加密技术、数码技术等方法实现通讯、控制、加密、延时等功能的工业雷管，具有延期范围广、延期精度高、安全性高、监管程度高等优点，近年来得到诸多应用[1]然而，尽管数码电子雷管优势明显，在使用过程中也面临着一系列挑战；尤其是在小断面爆破中拒爆率居高不下，严重影响了爆破效果[2]
为了有效、简便地评估数码电子雷管的抗冲击性能，有必要研究高过载冲击下电子雷管的损伤特征。（剩余8140字）
