Abstract�� An ASFD/MRR (Adaptive Squeeze Film Damper with Metal Rubber outer-Ring) was designed to improve the high non-linearity of oil film force of conventional SFD (Squeeze Film Damper). The ASFD/MRR can effectively reduce vibration due to its ability of automatically adjusting the film clearance by elastic deformation of the metal rubber. Experimental results indicated that ASFD/MRR can control the clearance of the film and its oil film force characteristics are better than those of SFD. If ASFD/MRR can markedly restrain the occurrence of nonlinear vibration phenomenon such as bistable characteristic, lockup and non-synchronous motion, it can be suitable for wider range of unbalance level.
