| 摘 要： | 根据灼热桥丝式电火工品的电热起爆机理,在桥丝药剂系统的物理传热过程中忽略桥丝药剂接触面的热阻和热容等假设条件下,建立其静电发火的理想数理模型。针对此模型方程提出了一种数值解法,并对解的结果进行了讨论。

| Abstract: | Based on the electrical heating mechanism of hot bridgeware electrical detonator ( HBED), an ideal mathematical model of electrostatic firing is built.In this paper,it is assumed that during the process of the physical heat conduction the heat resistance and the thermalcapacitance at the contact surface between the bridgewire and the explosive is ignored. A numerical method is also presented for the model equation and the result is discussed. |
