Abstract:

In order to cope with armored target with double explosive reactive armor, it is necessary to study the field of explosive reactive armor systematically. Based on the research on the flying plate motion law of the double explosive reactive armor, a theoretical model of applied field about double explosive re- active armor has been developed. Using the model, reaction time of double-layer explosive reactive ar- mor爷s applied field has been studied under the conditions of different arranged angles and wedge angles. The flash X-ray test is accomplished to verify the theoretical results. The results show that the arranged angle and wedge angle have a larger influence on explosion field, in the certain range, making reaction time of applied field improved about 1. 75 times. The calculation results have a good fit to the experiment results.
