| Abstract: | The effectiveness of variable parameter squeeze oil film damper (VPSFD) in the steady and transient unbalance response control of flexible rotors is examined.First, a preliminary property design of VPSFD is presented on the improved finite length bearing theory.VPSFD is different from the conventional squeeze film damper, and is designed to possess continuous changeable oil film clearance and land length. These parameters can be exactly adjusted on a computer by sending commends to a special control device. Then, a simple rotor system with VPSFD is investigated. The experimental results show that VPSFD can attenuate the rotor system resonance peak due to unbalance. |
