Abstract

The work aims to explore the impact initiation response of the long rod projectile hitting the cylindrical shelled charge under different landing conditions. ANSYS-LSDYNA dynamics simulation software was used to analyze the long rod projectiles with different axial angles β and radial angles γ through numerical simulation calculation. The numerical analysis method was used to calculate the p²t value of explosive charge under various working conditions. By comparing its p²t value and quantitative differences, the impact of different targeting conditions on the impact initiation response‌ of cylindrical shelled charge was analyzed. When the axial impact angle β =15° and β =30°, the radial impact angle γ had little effect on the impact initiation effect of the shelled charge; when β =60°, $\Delta {{p}^{2}}t$ and ∆γ had an exponential relationship, and when $\gamma =75{}^\circ $, $\Delta {{p}^{2}}t$ and $\Delta \beta $ also had an exponential relationship ($\delta_{\gamma}=c_{1}+c_{2} \mathrm{e}^{c_{3} \nabla \gamma+c_{4}}$). The comparison of the dimensionless growth functions of the two showed that the variation of the radial angular γ has a more significant impact on $\Delta {{p}^{2}}t$. The research results indicate that when a high-speed armor-piercing projectile penetrates a target, an axial angle β or radial angle γ with a certain large value is more likely to initiate the cartridge charge within a short period of time..
