STATIONARY DYNAMIC
CHARACTERISTICS ANALYSIS OF
NEW SQUEEZED FILM DAMPER*
Abstract:
Recur to multi-hole and better elastic characteristics of metal rubber (MR), a new squeezed film damper with MR (SFD/MR) throttle ring installed on the end of MR and MR damping ring installed on the radial direction of MR is implemented. Based on the D'alembert principle, a locomotion equation and the mathematical model of stationary response of SFD/MR system is put forward. It proves that the SFD/MR has better ability to resist unbalance loads than the traditional SFD after the stationary dynamic characteristics of the traditional SFD and the new SFD/MR are researched.
