某型航空发动机故障发生的量化分析与思考

Approaches on Trouble Quantitative Analysis of a Given Engine

在对某型发动机故障统计的基础上 ,进行故障发生的量化分析研究 ,探讨出故障发生频次与发动机样本、工作时间段、故障性质的变化关系。同时 ,对重复性故障及重大故障进行了专题分析 ,就维修性与可靠性指标进行了确定与评估。最后 ,在使用维护、改进设计、生产装配等方面提出了建议。

Based on the statistics of the troubles that happened in a given engine including their times,the appearances,the reasons,the characters,as well as the measure and the time for eliminating,quantitative analyses of the troubles have been made,and the variable relationships of the trouble-frequency with engine sample,engine operation time section and properties of the trouble have been found out.The monographic analysis has been focussed on the repeated failure and major failure.The reliability and maintainability index of the given engine have been evaluated.Finally,precautions during field maintenance are discussed,some suggestions are presented for its modification and production.
