Abstract :
The Reynolds equation with oil rupture boundary is solved based on database method. Nonlinear oil film force of combination journal bearing is obtained by retrieval, interpolation, and assembly techniques. As for symmetrical Jeffcott rigid rotor system supported by combination journal bearings, the nonlinear motion of the system is calculated by Poincaré map and self-adaptive Runge-Kutta method. Numerical results reveal rich and complex nonlinear behaviors and bifurcation.
