Abstract

The work aims to study the effect of the explosive charge density of reactive armor on its shooting resistance performance. Firstly, theoretical analysis was conducted on the mechanism of armor-piercing shells triggering reactive armor and the criterion for explosive charge triggering of reactive armor. It was found that the explosive charge density was one of the important affecting factors. At the same time, the effects of explosive charge density on the shooting resistance of reactive armor against the small caliber armor-piercing shells were studied by numerical simulation and experimental verification methods. Under certain test conditions, when the explosive charge density was 1.65 g/cm³, only three pieces of reactive armor were ignited by the armor-piercing shell and would not explode at all. When the explosive charge density was 1.25 g/cm³, two pieces of reactive armor were detonated. The experimental verification, theoretical analysis and numerical simulation conclusions were consistent. Once the charge density reaches the certain value, increasing the explosive charge density can raise the threshold for reactive armor to be triggered by impact.
