To improve the equipment miniaturization and reliability of weapons and ammunition systems, this study designs a micro-scale detonation train (MDT) with a built-in pyrotechnic microelectromechanical system (MEMS)-based safety and arming (S&A) device, which consists of an energetic semiconductor bridge (ESCB) detonator, and a S&A device with built-in isolation mechanisms, and a micro-detonation train. Furthermore, this study investigates the effects of the slider thickness, the spring beams’ thickness, and the positioning beam type on the security of the S&A device using the Finite Element Dynamics software and verifies the function of the MDT through experiments of capacitive charge and discharge ignition. As indicated by the results, an encouraging arming function can be achieved under a slider thickness of 1.0 mm and a positioning beam type of PB, while the spring beam thickness is less relevant. Additionally, the results show that the arming function of the MDT can be completed in 0.6 ms.

为了提高武器弹药系统装备的小型化和可靠性，本研究设计了一种内置基于烟火微机电系统（MEMS）的安全和武装（S＆A）装置的微型爆炸列车（MDT），该装置由高能半导体桥 (ESCB) 雷管、内置隔离机构的 S&A 装置以及微爆轰列。此外，本研究利用有限元动力学软件研究了滑块厚度、弹簧梁厚度和定位梁类型对S&A装置安全性的影响，并通过电容充放电实验验证了MDT的功能点火。结果表明，在滑块厚度为 1 的情况下可以实现令人鼓舞的解锁功能。0 mm 和 PB 的定位梁类型，而弹簧梁厚度的相关性较小。此外，结果表明MDT的布防功能可以在0.6 ms内完成。
