The Nonlinear Analysis of Thermal Stability and the Study of Global Stability of Periodic Solution of Thermal System of Thrust Bearings

The model of the thermal system of the thrust bearing considering the effect of transient pressures is established. The PNF method for investigating the bifurcation of the periodic solution of the system is used to study the thermal stability of thrust bearings. A new numerical method called PCM(Poincare-Cell-Mapping)is presented to investigate the global stability of the periodic solution of the thermal system of thrust bearings.
