Vibration attenuation mechanism of an adaptive squeeze film damper with metal rubber outer-ring(ASFD/MRR) was investigated. Based on static strength analysis and motional analysis of an ASFD/MRR and an axes-s neck of rotor, Reynold equations were deduced from Nevier-Stockes equation and liquid continuous equation,and pressure field of squeeze film was solved. Comparing vibration attenuation mechanism of ASFD/MRR with a squeeze film damper(SFD), the result indicates that SFD is a special form of ASFD/MRR. ASFD/MRR can markedly restrain the occurrence of nonlinear vibration phenomenon such as bistable characteristic and it can be suitable for wider range of unbalance level.
