In order to study the perforation characteristics generated by a spherical 2A12 aluminum projectile impacting cylindrical shell steel free beams at high-speed, the experiments of a spherical projectile loaded by a two-stage light gas gun impacting cylindrical shell free beams were performed. Simulations were carried out to study different factors such as projectile speed, cylindrical shell diameter and thickness that influence the perforation diameter. Our simulation and experimental results are basically consistent. An empirical correlation of perforation diameter and related parameters was deduced combining dimension analysis and simulation. The results show that the radial and axial perforation diameters increase with the increase of the impact velocity when the thickness and diameter of the cylindrical shell remains unchanged; the radial and axial perforation diameter decreases with the increase of the diameter of the cylindrical shell when the projectile velocity and thickness are remain unchanged; the radial and axial perforation diameters decrease with the increase of the cylindrical shell thickness when the projectile velocity and cylindrical shell diameter remain unchanged.
