Abstract

Abstract

In this study we examined the changing tendency of the shock wave energy, bubble energy, total energy per unit mass and the total energy per unit volume by analysis of the pressure-time curves, and analyzed the chemical reaction process of the Ti fiber explosive through the total energy per unit mass. The results show that the peak pressure and the shock wave energy of the Ti fiber explosive per unit decreases as the Ti fiber content increases, the bubble energy per unit mass increases with the increase of the Ti fiber content, the total energy per unit mass and its energy density increase with the increase of the Ti fiber content. With the increase of the distance between the sensor and explosive, the rate of the Ti fiber explosive's peak pressure decay is slower than that of RDX, while the tendency of the shock wave energy and the bubble energy per unit mass with different contents of the Ti fiber explosive is basically in keeping with the increase of the distance. The chemical reaction process of the Ti fiber explosive was also obtained through the total energy per unit mass.
