Analysis of Rubber Supported Hydrostatic Bearing Systems with Elastic BearingSurfaces

摘要

As alternative for lock gates, designed with rolling wheels over rails,hydrostatic bearing systems, also called externally pressurized bearing systems, are developed at the Technical University of Delft, in collaboration with RWS (Public Works). These bearings will be applied in a new project, 'the Orange lock gates' at Amsterdam. With hydrostatic bearings, the rails are changed for a slide surface. The above lock gate is carried by one circular bearing at both ends. For lock gates, to be designed in future, long rectangular hydrostatic bearings should rather be used. After a general introduction, this thesis presents tools for designing long rubber supported hydrostatic bearings with rigid bearing surfaces. In this, tilted bearing systems play a central role. Next, the effect of elastic deformation is studied, with the objective to obtain knowledge on unfavorable elastic deformations as well as on elastic deformations which play a favorable role with respect to following irregularities in the slide surface.
