Fixed-point rubbing characteristic analysis of a dual-rotor system based on the Lankarani-Nikravesh model

A dual-rotor system dynamics model is established for simulating the aero-engine vibration with unbalance-partial rubbing coupled faults. The main characteristics of the dual-rotor model are as follows: (1) the compressor disc and turbine disc are considered in both low pressure rotor and high press...
