| Abstract: | Considering nonlinear fluid film forces of a journal bearing, the time-varying mesh stiffness of the gears, friction effect between tooth pairs, and backlash clearance, a geared rotor-bearing system is modeled. It is shown that the motion equation of the system is a nonautonomous differential equation with strong nonlinearity. It contains plenty of dynamic phenomena. |
