Abstract

Abstract

The material and structure of a crisp airproof lid was determined. Numerical calculations on the crisp airproof lid impacted by rocket projectile and fired-gas streams were carried out by the finite element method, and simulated results were experimentally validated. Fracture effects and performances of the airproof lid were obtained. Researched results show as follows： (1) The airproof lid can fracture along the preset slot, satisfies the reliability of the fuze and doesnt influence the natural work of the rocket. (2)Impact forces of fired-gas streams have so little effect on the airproof lid that the airproof lid cannt be destroyed.
