摘要
以普通桥丝电雷管为试样,采用Hopkinson压杆应力波加载技术,在冲击加速度≥100 000g、过载脉冲宽度≥100μs条件下,进行了抗冲击过载性能试验,并对试后样品进行X射线CT层析扫描分析研究,获得了高过载下桥丝电雷管的失效模式与失效机理。研究结果可为桥丝电雷管抗高过载加固设计提供技术支持。
Based on the technique of Hopkinson pressure bar, the impact resistance performances of bridge-wire electric detonator were studied under the impact of acceleration over 100 000g, pulse width over 100μs in this paper. And then the test samples were analyzed by X-ray CT tomography scan, so the failure mode and failure mechanism have been obtained. It＇s useful for high overload reinforcement design of bridge-wire electric detonators.
