摘　　要：A squeeze film damper (SFD) with metal rubber (MR) ring installed on the end and the radial direction of rotor are implemented in this paper. Based on the hypothesis of π film, the description of the new SFD/MR flux and nonlinear oil film damping force is derived according to the Reynolds Eq. and Darcy’s law. It proves that the SFD/MR has better damping characteristics than the traditional SFD after comparatively analyzing characteristics of oil film between the traditional short SFD and the SFD/MR.A squeeze film damper （SFD） with metal rubber （MR） ring installed on the end and the radial direction of rotor are implemented in this paper. Based on the hypothesis of π film, the description of the new SFD/MR flux and nonlinear oil film damping force is derived according to the Reynolds Eq. and Darcy＇ s law. It proves that the SFD/MR has better damping characteristics than the traditional SFD after comparatively analyzing characteristics of oil film between the traditional short SFD and the SFD/MR.
