Vibration Analysis of Aeroengine Turbine Blade-Disc Coupling System

Abstract:

This paper introduces the FEA method for cyclic symmetric structures and makes an vibration characteristics analysis to a certain type of aeroengine turbine blade-disc coupling system based on this method. According to the analysis results, the dynamic characteristics of the blade-disc coupling system 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 turbine blade-disc coupling system.
