The damage experiments of simulation target′s vulnerability were made by using the real rod warhead to the charges covered steel shell. The damage effects of rod-fragments and shock wave overpressure were analyzed and the damage analysis was compared with the calculation of Jacobs criterion. It can′t detonate simulation target when pecific kinetic energy of 12 grams rod-fragments amount to 5.7 kJ·cm^-2 and blastwave overpressure amounts to 4.67 MPa through analysis of experiments results. If the velocity of rod-fragements increases to 2.3 km·s^-1,the fragments may detonate simulation target. The results show it is difficult to detonate the charges covered steel shell by rod fragments and shock wave, but they could damage the structure of the targets in appropriate conditions.
