Abstract

Abstract

In order to examine the overloading resistance performance and adaptability of primary explosive in detonator used for fuse, several typical primary explosives' mechanical conditions, failure character and overloading resistance capability in the simulating bomb was analyzed by the penetration experiment on concrete target. Results from test and calculation showed: The overloading value of tested bullet is 8.7×10⁴g, time is 2 ms, the maximal velocity is 708 m/s, penetrating depth is 0.57 m; The maximal transient acting force of primary explosives in inertial load is 85.34 N; Impulse is 70.17 mN·s; The maximal transient action energy is 0.466 8 J; The total energy is 18.656 1 J. Under this mechanical condition, the actual acting force aroused for acceleration is less due to primary explosive' less mass, and it is comparative to impact sensitivity potential energy at static state of primary explosive. No damage and failure of the primary explosive were found in the tested bullet.
