Description
Summary:In order to improve the reaction armor protection, this paper armours of interlayer charge and the thickness of the steel plate and charging ratio analysis, based on the reaction between armor and jet interaction, established the reactive armor and shaped charge of finite element model, using AUTODYN software, adopt the method of fluid-structure interaction for numerical simulation research. The results show that compared with other explosives, CL-20 has an ideal interference effect on jet flow. In the designed structure, the reactive armor with a steel plate thickness of 4 mm and a charge thickness of 8mm achieves the best protective performance.
