摘要：
Using magnetorheological (MR) fluid in place of lubricating oil in a traditional squeeze film damper (SFD) can build a variable-damping SFD controlled by an magnetic field, and can be used to control the vibration of rotor systems. The structure of an MR fluid SFD is introduced. The Reynolds equation of the MR fluid squeeze film is derived and solved based on the Bingham model, and the formulas for flowing velocity, pressure distribution, film force, and the magnetic pull force of the damper are presented. The mechanical properties of the squeeze film and the unbalance response characteristics of the MR fluid damper-rigid rotor system are analyzed theoretically.
