| Abstract: | This paper introduced the temperature rising models of bridgewire considering capacitor discharge and direct current as input energy, the temperature rising model of explosive and their numerical analysis methods. Meanwhile the energy balance equation for calculating sensitivity was presented and the theoretical method of reliability design of energy input for bridgewire electro explosive device was described. A numerical example was given to compare with the real product and the result showed that the models were available for theoretical calculation in reliability design of bridge wire electro explosive devices. |
