Abstract

Abstract

Apolyvinylidenefluoride(PVDF)pressuresensorwasdesignedandtwoequivalentmeasurementcircuitswereintroduced. ThedynamicsensitivityofthePVDFpressuresensorwascalibrated byusingasplitHopkinsonpressurebarsystem.Resultsshowsthatthedynamicsensitivitycoefficientshaveonlysmalldiscrepancyinthecasesofdifferentparallelresistancesandallthecali ration resultsareveryclosetothatgivenbymanufacture.Butthelargertheparallelresistance,thelonger therisetimeofthepulsedthrustgainedbythetestsystem.Obviously,selectingsmallerparallelresistancesisaneffectivewaytoobtainmoreauthenticsignals.
