Simulation and experimental study of fragment penetration into armored steel plate

In order to study the penetration ability of fragment simulation projectile(FSP) to armored steel target, and to detect the protection ability of target plates with different thicknesses. Combined with numerical simulation and experiment, the penetration process of FSP on armored steel target plates with different thickness ratios is studied. The design and implementation preparations were made for the damage of the steel target plate by the fragments, and the relevant data were obtained and analyzed. The analysis results show that the finite element analysis and the experimental study are in good agreement, and the ballistic limit of armored steel targets with different thicknesses and the calculation formula of the residual velocity of the FSP are obtained. The research results provide the basis and support for the evaluation, design and improvement of armored vehicle protection capability.
