Dynamic Characteristic Analysis of the Multi-Stage Centrifugal Pump Rotor System with Uncertain Sliding Bearing Structural Parameters

The traditional dynamic characteristic analysis of the multi-stage centrifugal pump rotor system is developed assuming the bearing structural parameters with constant values.However, the manufacturing errors will Snow Pants cause the structural parameters to vary around their nominal values and then affect the dynamic characteristics of the bearing
