电子雷管电子控制模块冲击动态响应与可靠性
Impact Dynamic Response And Reliability of Electronic Control Modules in Electronic Detonators
摘要
Abstract
To investigate the reliability of electronic detonator control modules under impact initiation,a single-impact and superimposed-impact experimental system was constructed using concrete test blocks.By controlling equivalent explosive sourc-es and equivalent spacing,the firing voltage range of the bridge wire was determined through the up-and-down method.The dy-namic response of the electronic control module under impacts with varying hole spacings was analyzed.The findings indicate that temporary failures and permanent damage can be distinguished based on the bridge wire firing voltage range and the voltage drop at the delay termination.If the voltage falls into the unstable range(12.989-14.421 V),the firing status must be further as-sessed based on the remaining voltage at the delay termination.Some capacitors experience continuous voltage decline after im-pact,increasing the risk of misfiring in long-delay detonation networks.The module's layout analysis within the casing reveals that tantalum capacitors exhibit significantly better impact resistance on the front side compared to the side,while chip perfor-mance remains largely unaffected by impact direction.Additionally,a comparison with continuous impact experiments shows that superimposed impacts exacerbate capacitor discharge phenomena.As the interval time increases,the coupling effect be-tween successive impacts weakens,allowing capacitors to achieve more complete recovery through internal self-healing mecha-nisms,thereby significantly enhancing charge retention under secondary impacts.When the interval time exceeds 200 ms,the voltage drop caused by the secondary impact decreases by approximately 60%compared to a 50 ms interval,markedly improv-ing the firing reliability of electronic detonators.关键词
