This paper introduces the FEA method for modal analysis of aero-engine turbine blade-disc system. Natural modal analysis for dynamical analysis and the result can be used as criterion of many dynamics characteristics and further analysis. In this paper, the natural modal of an aero-engine turbine blade-disc system with the turbine 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 turbine blade-disc system 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 blade-disc system.
