Abstract

Computer modelling of layered conformal contact J. McConnachie, M.J. Pagan Department of Engineering Design and Manufacture, University of Hull, ABSTRACT This work is concerned with a finite element investigation of conformal contact between cylindrical and spherical layered components to study the effects of material properties and load on the contact. The study stems from the analysis of the contact between the piston barrel and cylinder block and the piston ball and slipper seat of an axial piston pump but could apply equally well to any components with conformal cylindrical or spherical contact such as actuators or hip joints. The purpose of the research is to develop procedures to aid in the selection of lining, sleeve and seat materials which might be chosen for a particular property (eg. chemical resistance, low friction) and then fixed in or onto a standard, and generally less expensive, bulk material. The non- linear nature of the problem means that simple mater
