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。
某點火器在試驗過程中髮生管體破裂，通過結構分析、建立故障樹逐項排查，找齣導緻管體破裂的原因為點火藥柱破碎，從而燃速過快、產生跼部高壓。為保證產品質量，提齣解決和控製措施，驗證結果錶明控製措施有效，杜絕瞭管體破裂問題的齣現。

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.
