To familiarize PhD engineering students with basic concepts of tribology, this would be useful in explaining and enhancing main processes and performances of various machine elements. An objective of the course is to present students crucial need and necessity of taking tribological aspects in design process of machine elements, mechanical systems development and for design in general. Introducing in methodology, procedures and requested tools in aim to organize and conduct corresponding tribology experimental investigations on some typical machine elements.
Students who are attending to finish this course shall determine the general tribological phenomena and their application in the operation of typical machine elements. In accordance with the available equipment and facilities in laboratory they will introduce methods, types and elements needed for the implementation of the experimental research of machine elements, with emphasis on the creation of data acquisition using NI SCC module and transmitted the necessary software for data acquisition.
Introduction, of course, and summarize the basic concepts and phenomena in the field of tribology. The reasons for the necessity of consideration of tribological phenomena in the research and development of individual machine elements and systems. Introduction to Tribological Failure Analysis, Wear Analysis Process with Wear Mechanisms, Surface Examination and Characterisation, Contact Mechanics, Roughness, hardness, friction, Wear Testing; Properties of Lubricants; Lubrication Regimes with analysis; Design of Machine elements from aspect of Lubricants; Hydrodynamic Lubrication (Reynold’s Equation, Fluid and Pad Bearings, Plain Journal Bearings), Elasto-hydrodynamic Lubrication; Design requirements of ceramic and composite sliding contacts, wear and friction behaviour of alumina composites with silicon carbide and graphite as solid lubricants.
Introductory lesson. The concept of training on the subject. Getting to know the Machine design Department lab for mechanical elements investigation with the available equipment and the acquisition of data for experimental research. Types of equipment for data acquisition with the necessary elements. Dating with portable data acquisition system (NI SCC). Demonstration and practice of measuring temperature, stress and strain of machine elements.
should be useful in case of previous finishing course "Experiments and simulations" at MSc studies at group for Design in mechanical engineering (DUM)
available literature in form of books and International tribology conferences Proceedings, such as testing machines in laboratory for Machine elements (self lubricating sliding bearings, rolling bearings and gears)
