In order to research on damping mechanism of floating ring squeeze film damper
the model of floating ring squeeze film damper was established based on the Reynolds equation of squeeze film damper and relative movement of floating ring and journal. Then damping mechanism of floating ring squeeze film damper was researched by means of displacement response of rotor system and bidirectional incentives test system of floating ring squeeze film damper. It is shown that the greater mass of floating ring
the thinner oil clearance
the wider oil film width or the greater viscosity of lubrication oil
the better damping performance of floating ring squeeze film damper
Sudden unbalance response analysis of rotor system supported on floating ring squeeze film damper
Experimental comparison of vibration isolation ability of centralized and uncentralized squeeze film damper
Design method of squeeze film damper for aero-engine rotors
Identification of rotor-rubbing malfunctions in aero-engines
Nonlinear dynamic analysis and experiment verification of rubbing faults of rotor-ball bearing-support-stator coupling system for aero-engine
