EXPERIMENTAL STUDY OF TYPE 51 7.62MM BULLET PENETRATION TEST TO THE MINIBUS BODY AND ITS SIMULATED TARGET

The penetrating test of bullet impacting the minibus body was carried out to explore the bullet hole parameters and minibus materials composition. And then the body simulation target was established by analyzing the composition materials of minivan body and the result of penetrating test. The simulated target penetration experiments were carried out with different velocity and angle. The velocity range is from 100m/s to 450m/s, and the angle range is from 15 degrees to 90 degrees. The results show that with the same penetration angle, the width of bullet hole increases with the increase of penetrated velocity. When the angle is 30 degree and the velocity is less than 110m/s, the bullet cannot penetrate the target. When the angle is 15 degree and the velocity is less than 226m/s, the bullet cannot penetrate the target.
