Abstract

The paper presents a FEA method for an aero-engine compressor blade and makes a vibration characteristic analysis of this aero-engine compressor blade using this method. Computations are carried out to get the natural modal and corresponding frequencies of this compressor blade. The first eight natural frequencies and mode shapes are obtained and the vibration characteristics of this aero-engine compressor blade are discussed based on the results. The FEA method and the results in this paper are useful for further researches on structural optimal design and vibration safety verification for this kind of aero-engine compressor blade.
