| Abstract: | The impact resistance between the bore surface and skirt during the projectile squashing in the chamber at the high pressure is analyzed. The mathematical models are set up based on the special struc-ture of projectile skirt and barrel. The stress-time curve, velocity-time curve, and displacement-time are obtained with the mathematical models. And the effects of skirt and the initial speed of projectile are point-ed out. The research can provide the theoretical references to improving the projectile accuracy. |
