Abstract:	In order to study the penetration resistance of hyperboloid ceramic composite target against 12.7mm penetrating projectile, based on ANSYS/LS DYNA dynamics software,when the curvature radius R1 of the short axis is 0.43~0.83 m, and the curvature radius R2 of the long axis is 1.00~1.40 m, the penetration of a 12.7 mm projectile into a hyperboloid ceramic composite target plate is numerically simulated, and the ballistic limits of typical targets are obtained. When the angle is 15°~60°, the critical velocity of ricochet is obtained. The results show that the ballistic limit increases exponentially from the center to the edge of the target plate.When R1 is the same, the ballistic limit decreases with the increase of R2. When R2 is the same, the ballistic limit decreases with the increase of R1. At the same target, with the increase of the angle, the critical velocity increases exponentially. If R1 and R2 are fixed, the critical velocity of each target point decreases gradually along the negative axis X and increases gradually along the positive axis X at the same angle.
