Reliability Sensitivity Analysis of Bearing-Rotor System Based on the Dynamic Coefficient

According to components reliability sensitivity theory methods, looking upon the dynamic characteristics of hydrodynamic lubrication sliding bearing as the target for study, doing some reliability sensitivity analysis for the bearing-rotor system instability issues, numerical simulation results are given though analyzing. The outcome of the dynamic performance index is proposed based on the sliding bearing selection method for engineering practice to the selection of the radial journal bearing and provides a theoretical basis for overall design of shafting.
