Abstract

The analysis includes the oil film inertia and viscosity temperature effects.Based on the pad force equilibrium equations and the differential equations of motion, the dynamic model of the flexible bearing tilting pad bearing is was established.In this paper, an iterative calculation method to determine the flexure pivot tilting pad that bears the static equilibrium position is was proposed.The PDE toolbox was used to solve the static and frequency disturbance pressure Reynolds equation The Newton-Raphson iteration method could be used to calculate the static equilibrium position of the journal and the pad.The simulation results were compared with the experimental data, and the dynamic model and simulation method are verified.
