This article uses the transfer matrix method. The calculation of critical speed and unbalance response of a flexible dual-rotor system with high speed (30000 ~ 50000r / min) aeroengine is carried out. The vibration damping performance of the rotor system is analyzed with different oil film gap and damping coefficient of squeeze film damper Impact. The theoretical calculation value is consistent with the measured value. The mechanical model and the calculation program established in this paper provide theoretical analysis and calculation basis for the structural design and modification of the flexible twin-rotor engine.
