摘要：

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, vice versa. ©, 2015, BUAA Press.
