Abstract

In order to study the power capability of RDX-based PBX and determine the parameters of the JWL equation of state, the ∅50 mm standard cylinder test of RDX-based PBX and TNT were carried out, the expansion distance-time curve and velocity-time curve of the cylinder wall were obtained. Compared with the TNT, PBX had obviously a higher power capability. Based on the theory of energy conservation and the nonlinear fitting of the experimental data, the parameters of the JWL equation of state were obtained. Compared with the known software parameters and by numerical simulation of the cylinder test by AUTODYN, a fairly good agreement was reached between the experimental value and the actual test results, proving that this method for obtaining the JWL parameters is viable.
