耐高过载延期电雷管的设计

为提高延期电雷管耐冲击性能,对其加载作用过程进行了分析,对加固与缓冲结构、耐冲击延期技术进行了研究,并采用应力分解和对发火、传火、延期元件加固设计,环形储气空间设计,对其进行了设计。高冲击加载试验结果表明,该设计方法耐加速度冲击高于1×105g,可提高延期性能。

Design of Electric Delay Detonator Withstanding a High Acceleration Impact

The loading process was analyzed to improve performance of delay electric detonator withstanding a high acceleration impact. The consolidating and buffering structures, and delaying technology withstanding impact were also studied. The design of stress distribution, firing, auxiliary ignition, consolidating design of delay element,annular gas storage space structure design were adopted. Thereby, high impact loading test was carried out. Results show that the value withstanding acceleration of the above design structures is higher than 1×105 g and the delay performance is also improved.
