The Practical Application of Computers to the Design of Bearings in Automotive Engines 710548

There is a large amount of theoretical work available on the subject of hydrodynamic design of bearings. This paper describes how, with the use of computer aided techniques, the various factors involved in the bottom end design of automotive piston engines are developed.In the study of the behavior of oil film in a journal bearing, the problem has been to determine what simplifying assumptions were valid in order to present useful information at a low enough cost.Discussed in some detail are possible lubrication systems, material specifications, and hydrodynamic performance of the bottom end design of engines. With the use of correct simplifying assumptions, simple computer programs, and visual presentation, good use can be made of the available theory to aid the engine designer.
