为解决某火箭弹长期贮存后因点火回路失效造成火箭弹发射失败的问题,使用FMECA及FTA分析了点火回路的失效原因,提出了可疑故障点检测方法,并结合数据统计的分析结果,确定故障点为发动机中电点火头的批次性质量问题.实弹的解剖分析证明了此分析的准确性,为火箭弹的生产过程质量控制提供了依据.
為解決某火箭彈長期貯存後因點火迴路失效造成火箭彈髮射失敗的問題,使用FMECA及FTA分析瞭點火迴路的失效原因,提齣瞭可疑故障點檢測方法,併結閤數據統計的分析結果,確定故障點為髮動機中電點火頭的批次性質量問題.實彈的解剖分析證明瞭此分析的準確性,為火箭彈的生產過程質量控製提供瞭依據.

For solving the touching failure problem of rocket projectile,which has been storaged for long-term,the failure reason of the ignition system is analyzed using FMECA and FTA,and the detection method of the doubtful fault positions is proposed. Then the batch quality problem of the electric igniter in the engine is confirmed,by referring the analytical result of data statistic. The veracity of the analytical method is proved by anatomizing and analyzing the rocket projectile. The evidence of the quality control in the production for the rocket is offered.
