摘要
Abstract
In view of the aviation cockpit' s abnormal vibration in flying, firstly, the symptom and cause of aeroengine rotor' s typical fault were introduced. The probable cause of the aviation cockpit' s abnormal vibration was analyzed, and the cause of the abnormal vibration was judged preliminarily. Secondly, signal of aviation cockpit and aero-engine were collected by ground running aero-engine, then, the abnormal vibration frequency of aviation cockpit have been extracted from the collected signal, the frequency of aero-engine have been analyzed. Finally, the cause of the abnormal vibration has been found, the early fault of aero-engine rotor has been analyzed, and the analysis of the problem was referenced for the similar problems and faults of aero-engine.关键词
