| Abstract: | An experimental and theoretical investigation on the transient dynamic performances of a flexible rotor-SFDB system during passage through resonance is presented. The relationship among the boundary condition of oil-film pressure, unbalance load, speed range and jump phenomenon is discussed and a parameter of critical unbalance load for jump phenomenon,ucr, is introduced. The parameter ucr should be considered as the limit value of unbalance load of the rotor system in engineering designs. |

| Keywords: | squeezed oil-film damper through resonance jump phenomenon |
