Abstract

Abstract:

A multiple optimization method for virtual assembly balance of multi-disk rotors with multi-speed is proposed to meet the requirement of precise rotor vibration suppression in engine assembly. We establish a simulation model of the multi-disk rotor test rig， through which the virtual assembly is conducted， with known magnitude and phase of the residual unbalance of each stage disk and the original rotor vibration. Taking the residual vibration of each measuring point of the rotor and the overall unbalanced force and moment as the optimization objectives， the multiple optimization algorithm is used to find the optimization scheme of the mounting angle in each stage of the assembled disks. Experiments are performed on the test rig of the three-disk rotor system. The results show that this method can reduce the rotor vibration in a wide speed range with a maximum reduction of 85.75%. This study provides important methodological and technical support for engine rotor assembly.

Key words: multi-disk rotor, virtual assembly, multi-speed, balance, multiple optimization
