Abstract

Abstract

A method was raised by taking out the underwater explosion test to determin the JWL state equation parameters of detonation products. The PBX-01 explosive was applied and a calculating model of underwater explosion test was established by using ANSYS/LS-DYNA program. The JWL state equation parameters of detonation products for PBX-01 explosive were determined according to the comparison of the experimental and numerical results. Parameters determined by underwater explosion test and cylinder expansion test were used for detonation products driving water test. The results show that the underwater explosion test numerical simulation is accordant better in initial stage. Specially appointed patameters need to be established in the underwater explosions.
