The Mobility method was based on the infinite narrow bearing theory, so the analytic solution of oil film pressure could be obtained. Both the solving speed and the accuracy were quite satisfying, therefore, it found a widespread application in the bearing design. However, since the infinite narrow assumption was adopted and the oil feed features were neglected, the Mobility method was not available in precise bearing analysis. Based on the calculation ability of the intelligent system, Hahn's method was adopted in this book.

The characteristics of the three types of knowledge models are listed in Table 1-2. 6 Summary The tribological design methodology for an internal combustion engine is suggested to built using an intelligent computer aided design system, which aims at combining domain experiential knowledge with tribological theoretical analysis programs to directly and effectively deal with design problems. The core function of such an intelligent system is its decision-making mechanism and intelligent ability.
