Research on Turbine Disk LCF Life of Jet Engine

摘要:

结合某型涡轴发动机一级涡轮盘低循环疲劳寿命研究的工程实践,阐述了对涡轮盘低循环疲劳寿命研究的一般过程和方法,提出了涡轮盘低循环疲劳寿命试验的加载程序和方法,对开展同类型的涡轮盘疲劳寿命研究具有借鉴作用。

Abstract:

The low cycle fatigue (LCF) life was researched on the 1st level turbine disk, a key component of jet engine. Loading procedure was demonstrated in the engineering practice of turbo shaft engine LCF experiments. Fatigue life evaluation method was formulated according to turbo disk cycle experiments. It provides reference to similar studies.
