ME 597 Introduction to Friction and Wear (3 cr.) |
| Prerequisites: | ME 310 Fluid Mechanics or Graduate Standing |
| Textbook: | Williams, J.A., "Engineering Tribology", Oxford University Press, 1994
|
| Description: | Introduces engineering students to the fundamentals of tribology and its engineering applications. Topics include friction, wear and lubrication theories and how models can be appplied to assess and design against damage and failure of contacting structural components (mechanical & biological). |
| Goals: |
Energy losses due to friction and wear have major implications in machine performance. Some estimates predict over 20% of the worlds energy resources are spent in overcoming losses associated with friction. Friction and wear also have implications to the function of biological joints significantly affecting an individual's quality of life. This course develops a working understanding of the mechanisms, models and pratical design issues associated with tribological systems including bearings (journal, thrust, and roller bearings), gears, splines, slides, seals, axels, riveted lap joints, clutches, breaks, traction drives, aerospace engine attachments, and biological/articular joints to name a few. |
