Nonlinear Characteristics of a Geared Rotor System Considering Different Support Stiffness

Nonlinear Dynamic Model, Different Support Stiffness, Bifurcation Phenomena

the effects of different support stiffness on the nonlinear vibration of geared rotor systems were studied. The nonlinear dynamic model including both bearing clearances and gear backlashes was proposed. The influences of the excitation amplitude on the dynamic behavior of the system were discussed under different support stiffness. It was indicated that the different support stiffness could significantly influence the nonlinear dynamic response.
