Abstract: Based on the assumption of piecewise linearization of bearing stiffnesses and dampings, a offset rotor-bearing model with different rolling angles was established. Using DLAP software, coupled solutions of the offset rotor-bearing system dynamics model was presented. By means of eigenvalue and eigenvector, unbalance response analysis, stability analysis and transient dynamics analysis, the stability and safety of the rotor-bearing system were studied, and compared with that under normal operating conditions. The dynamics characteristics of rotor system supported by offset bearings under rolling conditions were obtained.

Key words: rolling condition, offset bearing, rotor dynamics, piecewise linearization
