To solve the vibration problem caused by rotor-stator rub failures with unqualified casing eoaxiality of an aeroengine, the principle and method of the aeroengine casing coaxiality measurenment were presented. The adjusting methods and measures were proposed. Many troubleshooting results show that the methods of turning flange and selecting eccentric ring are critical to solve rub failures of the aeroengine with unqualified casing coaxiality.
