Research on Bending Analysis and Performance Degradation Mechanism of Mass Mistuned Composite Rotor Caused by Disc Creep

Abstract

This paper will study the quantitative data of creep bending and performance degradation of combined rotors caused by mass mistuning, and its influence on the vibration characteristics of combined rotors, find out the causes of vibration intensification of combined rotors, and propose solutions, which will provide certain theoretical guidance for ensuring the safe and stable operation of gas turbines.
