Dynamic Characteristics and Stability of Short Wave Journal Bearings

A general analysis has been done to investigate the dynamic performance and stability of short wave journal bearing. Reynolds equation is solved for unsteady-state operations. The unsteady analysis has been used to determine the rotor dynamic coefficients for various eccentricity ratios and wave ecc...
