    Abstract
  • Toprovidethereliablemechanicalparametersofthefusesduringpenetration,itisnecessarytostudythedecelerationoftheprojectiles. Thepenetrationtestwascarriedoutforareduced-scale advancedearthpenetrationwarhead(EPW)intoconcrete.Thedeceleration-timecurveoftheprojectilewasobtainedbyahardrecoverytechnique. Thetestingsystemfordecelerationishighlymodularized, includingatestingmodule,acircuitmodule,amemorymodule,apower-supplymoduleanda peripherycomputermodulefordataprocessing.Inthetestingmodule,thepiezoresistiveaccelerometerisfabricatedbytheMEMStechniqueanditworksinaWheatstonebridge. Theprojectilemassis about1.8kg,includingthedecelerationtestingequipmentloadedinit.Themaximumdiameterofthe projectilesis48mm,andthestrikingvelocityis1142m/s.Thedecelerationmagnitudeobtainedby theexperimentisapproximately20104g.
