Fragmentation And Shock Wave Composite Role, Damage To The Missile

This article studied multiplex damages that the shock wave and the fragments do to the cruise missile. First, analyzed the basic form, the structure, the dimension and the damage mechanism of the cruise missile, and then used the intension-equivalent method to get the missile' s equivalent model under this kind of damage-form. Second, (1)set up the damage model that the prefabricated roundness fragments attack the missile, and then work out the damage probability through analyzing the number of fragments that hit the target, the incidence parameter of the fragments. (2) set up the damage model that the shock wave attack the missile, described the parameters of the shock wave, such as the peak value pressure, the press time, the velocity that the shock wave spreads, and then studied the damage that they did to the missile structure with the knowledge of dynamics. At last, take detonator quality, distance between exploding point and the missile, surroundings' pressure, size of the missile and the capability against impulsion of the missile into account, we carried through a series of numerical imitate calculations in using the programmers compiled, and then obtained a lot of different results when the warhead attacked the missile at different time, on different location and with different detonator quality. The results are according with the physics rule basically.
