Abstract

According to the engineering application requirements of special-shaped section penetrating projectiles, the structural response and optimal design of elliptical-section penetration projectiles were studied. From this point of view, an improved general design method of elliptical-section projectiles was developed by introducing a dimensionless cartridge thickness coefficient of the elliptical projectile. In order to improve the inertia moment and static moment to the short axis of the cross-section, a bending optimization design method of the elliptical-section projectile was proposed by reducing the cartridge thickness of the projectile to a certain extent and redistributing the reduced materials. Based on a 152-mm-diameter light gas gun test device, the reverse tests of three kinds of elliptical-section hollow projectiles with the long axis of 1.8 cm and the short axis of 1.2 cm penetrating a 2024-O aluminum target were carried out, and the responses of the projectiles in the penetration process were obtained. The projectiles after tests were collected by the soft recovery method, and the deformation of the central axes of the projectile was obtained by the gray processing method. Numerical simulations of the tests were carried out by LS-DYNA. The stress, strain, and penetration load of the projectiles during the penetration process were obtained, and the equivalence of the normal ballistic test and reverse ballistic test was verified. Based on the free-free beam theory, a bending response calculation model of the elliptical-section projectile was established. Through the optimized design, the inertia moment to the short axis of the elliptical section increases by 16.44%, and the static moment increases by 15.95%. Under the test conditions, the bending deflection of the projectile decreases by 25.25%. The structural response model was used to calculate the projectile deformation under the test conditions. The calculation results of the theoretical model are in good agreement with the test results, which shows that the calculation method of the model has a certain accuracy and can provide a reference for engineering design.
