Abstract

This paper introduces the FEA method for vibration characteristics analysis of a certain type of aero-engine compressor disc. Natural modal analysis for dynamical analysis is made and the results can be used as criterion of many dynamics characteristics and further analysis. In this paper, the natural modal of an aero-engine compressor disc with the joint hole fully constrained and in free status is calculated respectively. And the first ten natural frequencies and mode shapes are obtained. Also, vibration characteristics of each natural modal and the corresponding influence on the compressor disc and other structure are discussed. The analysis method and results in this paper can be used for further study on optimal design and vibration safety verification for the compressor disc system.
