Lubrication, Friction and Wear

ME55600

Credit Hours: 3

Learning Objective:
Not available

Description:
Science, technology, and application of lubricated interacting surfaces in relative motion. Advanced analysis techniques and hands-on exposure to modern experimental methods provide an enhanced understanding of fundamental principles of lubrication, friction, and wear. Basics of design and analysis of machine components operating in the presence of air and liquid lubricants. Rolling fatigue, friction and wear models, and measurement techniques. Offered in alternate years. Spring 2017 Syllabus

Topics Covered:
Introduction - History of Lubrication, Friction and Wear, Definition of conformal and non-Conformal Contacts, Regimes of Lubrication; Lubricants, Newtonian, non-Newtonian, Units, Grades, Pressure and Temperature Dependence, Surface Measurement Techniques (Contacting & non-Contacting); Surface Parameters of Interest, Bearing Materials;Viscous Flow, Petrov's law, Navier Stokes Equation, Continuity Equation, Viscometry; Types of Bearings, Journal, Thrust, Rolling Element, etc., Bearing Materials, Fundamentals of Lubrication (Reynolds Equation); Physical Significance of Terms in Reynolds Equation, Hydrodynamic Thrust Bearing (Analytical Solution); Hydrodynamic Thrust Bearing (Analytical Solution, Hydrodynamic Thrust Bearing (Numerical Solution; Journal Bearing Analytical Solution, Short and Long Width Journal Bearing Theory; Dynamically Loaded Journal Bearing, Summerfeld Solution; Hydrodynamic Squeeze Film Bearing, Hydrodynamic Squeeze Film Bearing; Lubrication of Non-Conformal Contacts (Hydrodynamic), Hertz Stress Theory & Deformation in Dry Contacts; Non-Dimensionalization, Lubrication of Non-Conformal Contacts (Elasto-Hydrodynamic - Line Contacts); Lubrication of Non-Conformal Contacts (Elasto-Hydrodynamic - Point Contacts), Lubrication of Non-Conformal Contacts (Elasto-Hydrodynamic - Point Contacts); Lubrication of Non-Conformal Contact

Projects:
50%-The project is an assigned, individual work, relevant to the course objective with a 10-minute presentation. You may need to conduct a literature search on the subject matter. You may need to develop computer software or use available software (i.e. ANSYS, Algor, etc.) to complete the project assignment. You are required to provide a typed, well-written document on your findings. You will need to develop computer models to complete the project assignment. Knowledge of numerical methods is quite helpful.
