Abstract: The external pipelines of aero-engine usually work in vibration condition, which is prone to cause vibration fatigue damage and failure. According to the vibration fatigue life estimation method theory, the vibration fatigue life estimation methods of aero-engine external pipelines in time domain and frequency domain are analyzed. The applicable characteristics of time domain method and frequency domain method for life estimation of aero-engine external pipelines are given. This paper can provide a theoretical basis of vibration fatigue life estimation for aero-engine external pipelines.

Key words: vibration fatigue, aero-engine, life estimation, pipeline vibration
