This paper commemorates Ramsey Gohar by acknowledging his contributions to the fields of contact mechanics and elastohydrodynamic lubrication (EHL) within context developments these subjects. A historical discourse is provided on elastohydrodynamics, from its inception in 1940s present. We demonstrate that was not only a pioneer discoveries fundamentals subject, but also led or contributed sign...

Abstract

Using finite element method and multi-body dynamics method, this study established an engine digitalized virtual prototype embraced tribological characteristics in virtual prototype and MATLAB platform, and introduced Elastohydrodynamics theory into the system, wrote program with difference equation method, and solved the Reynolds Equation through shafting-bearing self-feedback control system, ...
