| 摘 要： | 航空发动机寿命监视技术对监视发动机的工作状态、寿命消耗、剩余寿命和保证发动机在高性能水平下安全、可靠地工作有十分重要的作用.本文所设计的地面监视系统功能包括,对发动机飞行参数进行筛选并提取出影响低周疲劳寿命的循环数以及计算离心负荷、热负荷作用下的低周疲劳和蠕变寿命消耗,建立各关键件在低周/蠕变交互作用下的实际寿命消耗的计算模型.通过发动机使用寿命数据库对各监视零件的剩余寿命加以管理,为使用和维修提供参考依据.

| Abstract: | It takes very important role that aeroengine load and life monitoring technology in monitoring and assessing operating condition, life consumptiom and remaining life of aeroengine. It can improve the safety and reliability, and reduce direct usage cost of engine. In this paper, the life usage monitoring system is including data condensing processing,LCF counting for every flight and Low Cycle Fatigue, Thermal Fatigue, Creep, and any combination of them can be dealt with. The information obtained by life monitoring system is very useful for the database of part management which will be used to track the life usage of the engine parts. |
