摘要：
To research the prevention of sudden unbalance response of rotor system supported on floating-ring squeeze film damper (FSFD), a dynamic model of the rotor supported on FSFD was established. In the model, the coupling effect between rotor and FSFD was considered. An efficient numerical integration approach was employed to conduct the investigation into the dynamic response of rotor. The main results are as follow: compared with traditional squeeze film damper, FSFD has better performance in preventing both sudden unbalance response of rotor and transient process when the rotor speed approaches the critical speed; the greater mass of floating ring or viscosity of lubrication oil means better performance of FSFD in preventing sudden unbalance response.
