According to the theory of cavity expansion, the normal and tangential expansion forces on shell surface of kinetic warhead penetrating concrete are analyzed, and the force calculation model of warhead is established. Based on the rigid body kinematics theory, differential equations of penetration of kinetic warhead are established , The mechanical response of the kinetic warhead penetrating the concrete under different angles of attack and angles of attack was calculated through programming, and the influence laws of the falling angle and the angle of attack on the maximum resistance and the maximum resistance moment of the kinetic warhead were obtained. Strength design and jumping performance provides the basis for the study.
