FUNDAMENTALS OF MICROSYSTEM DESIGN

概要

Fundamentals of Tribology deals with the fundamentals of lubrication, friction and wear, as well as mechanics of contacting surfaces and their topography. The lecture will begin by introducing the importance of tribology in everyday life and offers a brief history of this engineering field. It then describes the nature of rough surfaces and the mechanics of contacting elastic solids and their deformation under load and friction in their relative motion. The lecture will further discuss the importance of lubricant rheology with respect to viscosity and density. Then, the principles of hydrodynamic lubrication are covered with derivations of the governing Reynolds and energy equations. Applications of hydrodynamic lubrication in various forms of bearings — journal bearings, thrust bearings will be outlined.

目標

The goal of this course is to explore the world of Tribology and its usage in our daily lives and in various engineering systems. This requires an awareness of material properties, surface treatments/modifications, fluid mechanics, rheology and so on. We will cover this through a combination of lectures, case studies, homework, and journal presentations as final assignment.
