Hydrodynamic bearings allow the various parts of mechanical devices to be driven easily while ensuring a reliability which eliminates any risk of rupture or premature wear. When the operating conditions are severe (high or quickly varying loads, great rotational frequency) it becomes difficult to achieve this double goal without the assistance of powerful prediction digital models.
This 4-volume series of books brings together the elements necessary for the realization and the validation of these tools.
After the presentation of the characteristics of rough surfaces this second volume of the series presents several models for the digital study of mixed lubrication and the wear of bearings. Many examples relating to the bearings of internal combustion engines illustrate the possibilities of these models.
These books are of great interest both for researchers wishing to extend their knowledge of the behavior of connecting rod and crankshaft bearings of internal combustion engines and for engineers aiming to develop equipment that reduces engine energy losses while increasing their reliability. The analysis, modeling and solution methods presented here are sufficiently general to be applied to all reciprocating systems, such as, for example, piston compressors.
