Abstract

This essay made study of gyroscope rolling-rotor system. The composite stiffness under the state of elasto-hydrodynamic lubrication and nonlinear contact force considered the effects of minimum oil film thickness were calculated. A dynamic equation was established considered the calculated stiffness and bearing force and was numerically solved to obtain the bifurcation diagram, Poincaré maps, spectrum, phase diagrams and shaft orbit with changes of speed and radial clearance to analysis the nonlinear dynamic response of the system. The results showed that: under EHL state, with changes of speed and radial clearance, the system appears various forms of response, and there is a period-doubling bifurcation phenomenon.
