Analysis and Computation on Dynamic Characteristics of a New Style Hydrodynamic Journal Bearing

This thesis completes 3D variational modeling design and Finite Element Simulation of a new style hydrodynamic bearing by I DEAS software,based on studying 3D solid modeling theory and Finite Element Simulation technology carefully and deeply.This thesis analyses the static and dynamic characteristics of bearing,computed the eight dynamic coefficients of oil,analyses the characteristics of this bearing after comparing with the other bearings
