Research on Lubrication Properties of Water-Lubricated Rubber Bearing Based on Fluid Structure Interaction

Abstract:

The 3D computational fluid dynamics (CFD) model and fluid structure interaction (FSI) model of water-lubricated rubber bearing with 10 axial grooves was built by ADINA and the influences of axial velocity, rotating speed on deformation of bearing bush and distribution of water film pressure are researched in this article. The results show that elastic deformation of bearing bush reduces water film pressure relative to rigid assumption; with the increasing of axial velocity, the deformation of bearing bush and water film pressure increases; and the axial velocity has a obvious influence on the front of bearing bush and water film pressure; with the increasing of bearing rotating speed, the deformation of bearing bush and water film pressure raises, but the deformation of bearing bush and water film pressure in water grooves are almost close to zero.
