“…The reason is that the pressures become so high that elastohydrodynamic lubrication occurs, and it is necessary to solve both the Reynolds' equation and the equation that describes the elastic deformation of the bearing surfaces. This is generally a time consuming calculation that requires a numerical treatment either by the finite element or finite difference techniques [35][36][37][38] .…”

We review some of the key tribological issues of relevance to motorsport applications. Tribology is the science of friction and wear, and in a high performance engine, friction and wear are controlled by good component design (e.g. the engine and the transmission) and also by the use of high performance lubricants with the correct physical (and chemical) properties, matched to the machine they are used in. In other words, design of a specific lubricant for specific hardware can lead to optimised performance. (Tribology is also important in the tire-road contact but is not considered here.) The importance of key physical properties of a lubricant is demonstrated with an emphasis on how the choice of the correct lubricant can help to minimize engine friction (and thus increase available power output) whilst protecting against engine wear. Key lubricant parameters discussed in the paper are the viscosity variation of a lubricant with temperature, shear rate and pressure. The relevance of these parameters in controlling oil film thickness and friction in bearings, the piston assembly, and the valve train is demonstrated with examples showing how a high performance engine differs from more conventional engines.

“…The paper on the elastohydrodynamic lubrication of journal bearings by Fenner et al 36 is particularly illuminating. The authors find that under high loads, there is a central portion of the bearing where the oil film thickness is essentially constant, and where the pressure distribution is effectively that of a Hertzian contact.…”

“…After that, a sliding bearing was randomly taken out to observe the metallographic structure under a metallographic microscope and the bonding status of the joint interface under a scanning electron microscope (SEM). Next, three test bearings were mounted on the sapphire fatigue test machine [16][17][18][19] in sequence and subjected to fatigue tests in accordance with the test procedure. Finally, the test results were analyzed in depth.…”

The babbitt-steel bimetal sliding bearing material prepared by the MIG brazing has been applied in many fields. In the application, usually only the bonding force is tested, and the fatigue strength is not evaluated. For this reason, this study referred to the test method for the fatigue strength of bearing materials of internal combustion engines, used the sapphire test machine (Dana Glacier Vandervell Bearings, UK) to inspect the SnSb11Cu6 babbitt-steel bimetal material prepared by MIG brazing, and analyzed the test results in depth. The test results show that, the fatigue strength of the bimetal material is more than 40 MPa. In comparison, according to the same test method and conditions on the same sapphire test machine, the fatigue strength of the SnSb11Cu6 babbitt-steel bimetal bearing material obtained by the centrifugal casting method after optimizing process was usually around 35 MPa. Therefore, the MIG brazing could produce higher fatigue strength for SnSb11Cu6 babbitt-steel bimetal bearing material. In addition, in this study, the process of fatigue failure was usually that after the microcracks were generated on the surface, they expanded to the inside of the lining, thereby resulting in spalling. This study has guiding significance for engineering practice and scientific research.
