Vibration analysis of rotating shaft ontextured hydrodynamic journal bearings

Abstract : The aim of this study is to analyse the influence of surface texturing on the dynamic behavior of a shaft on twohydrodynamic bearings. A prediction algorithm is presented with Fluid Structure Interaction (FSI) between the rotating shaftand the lubricant based on finite element method. Cavitation in bearings is taken into account. The hydrodynamic flow inthe texturing pattern is modeled by two multi-scale algorithms. Static, modal and transient analyses are performed in order topredict the impact of several texturing patterns on the system vibrations.
