【摘要】 某点火器在试验过程中发生管体破裂,通过结构分析、建立故障树逐项排查,找出导致管体破裂的原因为点火药柱破碎,从而燃速过快、产生局部高压。为保证产品质量,提出解决和控制措施,验证结果表明控制措施有效,杜绝了管体破裂问题的出现。更多还原

【Abstract】 The tube of some igniter was ruptured during the test, through structure analysis and fault tree analysis, the reason for the tube rupture was found out. It showed that the broken pellets lead to faster burning rate and high pressure partly. Meanwhile, the control measures were proposed, which were verified effectively, and the quality of igniter is ensured.更多还原
