【Abstract】 Using the loading technique of electrical explosion of metallic foil driving the polyester film flyer to produce short-duration pulse shock wave,the shock initiation characteristics of a TATB/HMX based explosive were studied according to the DRM(delayed Robbins-Monro) test procedure.Both the shock initiation thresholds under the condition of 50% initiation probability and the minimum initiation thresholds under the condition of 100% initiation probability were obtained.And by means of the diagnostic technique of optical fibre probe,optical-electrical converter,and digital oscillograph and the method of cylindrical wedges of explosive material,the run distance to detonation was measured as a function of initial shock pressure in the studied explosive,and the effect of pulse duration on the initiation and growth to detonation characteristics was considered.The results in the form of Pop plots were presented.更多还原
