This paper studies the simulate calculation about the coordinates of burst based on Monte Carlo method and the projectile fragments scattered point coordinate .According to scattered point coordinates in fried and the projectile fragmentation, this paper puts forward the concept of penetration coefficient; and through calculating the penetration coefficient, it comes a conclusion that the bigger the coefficient becomes, the probability of target damage is higher. It calculates the probability of a single fragment penetrating target and the overall target damage by using the calculation method of probability distribution. The dynamic simulation of debris’ kinetic penetration and the simulation of the changes of energy and the damaged probability are carried out. In this way, the results of the simulation are analyzed, which verifies the correctness of the theory.
