摘要
电爆炸桥箔是冲击片雷管的重要组成部分,其电导率是电爆炸过程中的重要参数。在分析桥箔状态变化的物理原理基础上,提出了将电导率分3个阶段来讨论:桥箔加热初始阶段、本征爆炸阶段和等离子体阶段。根据各个阶段的特点,建立了电爆炸过程桥箔电导率的计算模型。用此模型模拟的结果与实验结果具有很好的一致性。
The electric exploding foil is an important component of slapper plate detonator, and its conductivity is a key parameter of electric exploding process. The conductivity was discussed from three phases, i.e. early heated, intrinsic exploding and plasma, by analyzing the physics principle of the change of foil state. A computational model of conductivity of foil in an electric exploding process was established based on the characteristics of each phase. The simulated results of the model coincide well with the experimental results.
