| Abstract: | The initation characteristics of bridge wire are simulated by solving the electro-thermal equation with Runge-Kutta method in C language. The influence effects on the bridge wire temperature are discussed including heat dissipation, current strength, bridge the length, construction and heat capacity both in initiation by capaditor discharge and constant current. The reliability is clemenstrated by the comparison of bridge temperature curves between simultion and experimentation. A new method is provided for the computer optimized design of the bridge the initiators. |
