Abstract

This paper analyzes the assembly deformation of the aero-engine high-pressure rotor simulation tester, establishes the dynamic model of high-pressure rotor nonconcentricity, simulates the vibration response of the nonconcentric rotor, and verifies the correctness of the dynamic model of rotor nonconcentricity through tests. The results show that the rotor axis line is tapered when there is endface deviation, and the deformation is mainly concentrated in the front end of the tapered drum and the connection surface of the turbine rear journal, and the assembly parameters such as the bolt pretightening force and the number of bolts have little effect on the rotor assembly deformation; in addition, rotor nonconcentricity causes an increase in the rotor vibration amplitude, and the failure characteristics of frequency-doubled appear at the connection structure with endface deviation.
