Vibration Characteristic Investigation of the Counter-Rotating-Dual-Rotors in an Aero-engine

摘要：

Methods based on the MSC.NASTRAN platform for vibration characteristic investigation of the Counter-Rotating-Dual-Rotors in an aero-engine was put forward and the sequence was developed. For a start, vibrational characteristic of the Counter-Rotating-Dual-Rotors in a certain aero-engine was studied, then results were analyzed comparing with other method. It is proved the methods are valuable for vibrational characteristic investigation of high thrust-weight ratio aeroengine.
