Course Contents | Introduction: Understand and describe the main laws and concepts of Tribology, identify Tribological phenomena,describe factors that influence tribological phenomena, explain the regimes of lubrication and the origins of the Stribeck curve. Engineering surfaces: Describe methods for measuring surfaces, Identify finishing processes from a measured surface profile, describe and explain the most commonly used parameters in surface finish analysis Contact of engineering surfaces: Explain the Hertzian theory of contacting surfaces,Define and solve smooth body contact problems, including estimations of the contact pressure and real area of line and circular contacts.Understand and solve simple problems associated with the friction and temperature rise of dry smooth contact. Intoduction to friction and wear theories: define Amontons’ Laws of friction, describe sliding and rolling friction and compute the frictional force and the coefficient of rolling friction for a sphere rolling on a plane and a roller on a plane,Understand and define types of wear and classification system of wear mechanisms (mild and severe).Identify the actual physical mechanism of wear (adhesion, abrasion, oxidation, delamination, corrosion, melting, fretting etc.)Describe wear debris analysis, Ferrography. Intoduction to Hydrodynamic lubrication: Derive Reynolds equation and list and explain the main assumptions underlying this equation and its subsequent approximations.Use of the mobility method to design a journal bearing Intoduction to EHL and mixed lubrication theory: Describe and explain the lubrication of concentrated contacts (Martin solution and the half Sommerfield solution). Estimate lubricant film thickness, pressure, friction and temperature in elastohydrodynamic lubricated contact and in mixed lubrication | ||||||||
