Abstract
Abstract: In order to study the trajectory deflection law of projectiles obliquely penetrating into concrete targets, based on the theory of rigid body kinematics and cavity expansion, the penetration motion differential equations of ogive-nosed projectile were established. The variation rules of trajectory offset and invasion depth were given in different initial conditions through the programming calculation and numerical simulation by MATALB and ANSYS-LYNA software. The calculation results agree well with experimental data. The results show that the influence of penetration depth and deflection angle increase with the oblique angle increasing. The influence of ballistic deflection decreases with the impact velocity increasing. The ballistic deflection of projectile with ogive-nose is smaller, its performance against the ballistic degradation is high and its penetration trajectory is stable. The research results can provide some help for the oblique penetration trajectory analysis and the design of the projectile.
