电子雷管用电子控制模块的抗冲击性能研究

针对小断面爆破时电子雷管内电子控制模块易受冲击作用失效的问题，通过钢桶冲击实验，对工作状态的电子控制模块及其核心部件分别进行抗冲击性能研究。结果表明，电子控制模块受冲击作用后，相比于物理结构损坏，易出现内部储能电容失电现象。电子雷管用储能电容受冲击失电是固有特性。储能电容受冲击失电性能由强到弱的顺序为：固态铝电解电容、电解铝电容、固态钽电容。储能电容受冲击失电量与电容类型、受冲击强度以及管壳内部防护结构的设计相关。设计的钢桶冲击实验方案能定性研究电子控制模块及内部元器件的抗冲击性能，可用于生产实践中对雷管结构设计和元器件进行筛选，从根本上控制产品质量。

Impact Resistance of Electronic Control Module for Electronic Detonators

Aiming at the failure of the electronic control module used for electronic detonators under the impact action during small section blasting, impact resistance of the electronic control module and its core components in working state were studied through impact test of steel barrel. Results show that compared with the damage of physical structure, the electronic control module is more likely to lose power of the internal energy storage capacitor when it is affected by impact. Impact power loss of the energy storage capacitor used for electronic detonators is its inherent characteristic. The order of power loss of energy storage capacitor under impact from large to small is solid aluminum electrolytic capacitor, electrolytic aluminum capacitor and solid tantalum capacitor. The impact loss of capacitor is related to capacitor type, impact strength and the design of internal protective structure of shell. The designed steel barrel impact test can qualitatively study the impact resistance of electronic control module and internal components. It can be used in the design of detonator structure and the screening of components in production practice, and fundamentally control product quality.
