  • The disk-rod-fastening rotor dynamics model with squeeze film dumper(SFD) was built,and nonlinear differential equation method with multiple periodic solution was used to solve those equations with different combinations of system parameters;the influence law of bistable vibration characteristics of disk-rod-fastening rotor with SFD was studied,and the models' dynamic characteristics of stable system periodic solution with and without SFD were compared.The frequency spectrum analysis shows that the disk-rod-fastening rotor without SFD presents fundamental frequency vibration on bistable state,but that with SFD presents frequency multiplication besides fundamental frequency vibration.
