摘要
The dynamic model of a cracked centrifugal Impeller-rotor with both nonlinear lateral fluid force and nonlinear oil-film force was built and the dimensionless differential equations of the system were derived. The system's bifurcation characteristics were studied using the numerical integral method. The influence of the nonlinear lateral fluid force and the depth of the crack on the system's dynamic characteristics were analyzed in detail at last.
