摘要:
为提升火工品的作用可靠性，探索储存环境对火工品性能的影响，依据有关标准对某引爆装置进行了长期储存试验。试验结果显示，该引爆装置在高温储存试验后出现了电阻超差现象。采用故障树分析法对失效模式与失效机理进行了分析。研究表明，长期的湿热环境引起了金属焊锡丝、桥丝、脚线界面应力的差异，使得虚焊焊点瑕疵放大，导致电阻超差，从而失效。
Abstract:
In order to improve the reliability of initiating devices and explore the influence of storage environment on their performances, the storage test of an initiating device was carried out according to relevant standards. Results show that the resistance of the initiating device is out of tolerance after the high temperature storage test. The failure mode and failure mechanism were analyzed by fault tree analysis. It shows that the long-term humid and hot environment has caused the difference in the interface stress of metal solder wire, bridge wire and pin wire, which magnifies the defects of the faulty solder joint, leading to the excessive resistance and failure.
