Abstract EN
The magnetic suspended dual-rotor system (MSDS) can effectively increase the thrust weight ratio of aeroengines.
However, the MSDS dynamic characteristics have rarely been investigated.
In this research, a MSDS with the outer rotor supported by two active magnetic bearings (AMBs) is designed, and the PID control is employed.
The Riccati transfer matrix method using complex variables is adopted to establish the MSDS dynamic model.
Subsequently, the influences of AMBs’ control parameters on the MSDS dynamic characteristics are explored.
According to the analysis, two rigid mode shapes remain unchanged with the variation of the relationship between their corresponding damped critical speeds (DCSs).
Moreover, the rigid DCSs disappear with large derivative coefficient.
Eventually, the validity of the dynamic model and the appearance of rigid DCSs are verified.
