Abstract:To solve the aeroergine vibration failures, three typical failure of aeroengine vibration were concluded by the texting results. The vibration failures caused by the thermal bowed rotor, rotor-stator rub interaction and out of position for oil hole. The characteristic of vibration failure was illustrated. The reason is self-exciting vibration caused by the out of position for oil hole. The good failure elimination result proves that the methods are valid
