Lectures

Goal

Demonstrate knowledge and understanding in the field of machine elements research, based on the current professional knowledge, general knowledge of research methodology, as well as the specific methods of chosen research field (a specific machine element or group of elements, а general methodology for calculating and checking the operational ability of machine parts). Research in the machine elements field implies an analysis of their operational ability in terms of all relevant influences of geometry, mechanical properties of materials, operational conditions (load, speed, frequency, temperature, lubrication...), friction and wear, maintenance, and reliability. Considered machine parts and elements are obtained by conventional manufacturing and processing technologies, as well as by additive manufacturing technologies.

Outcome

At the end of the course, in the field of Machine elements research, student should be able to: - identify and formulate questions autonomously and creatively, with scholarly precision, critically, to select and apply appropriate methods, to undertake a limited part of the research and other professional activities with predetermined time frames, as well as to critically assess the expected results; - to present and discuss research results; - demonstrate the skills needed to participate autonomously in research and development work.

Theoretical teaching

Review and recap of knowledge obtained in the field of mechanical elements and review the importance of scientific disciplines that are the basis of the study of machine elements. The operational ability of machine elements and all relevant influences. Geometry (shape and size) of machine elements. Materials of machine elements (mechanical properties). A load of machine elements. The load-carrying capacity of machine elements. Load distribution in different machine elements (phenomena description and distribution parameters). Vibration and noise of machine elements. Types of damage and failure analysis of machine elements Tribology of machine elements (lubrication, friction and wear). Reliability and service life of machine elements. Condition monitoring and maintenance of machine elements. Considered machine parts and elements are obtained by conventional manufacturing and processing technologies and by additive production technologies.

Practical teaching

Introduction to the analytical, numerical and experimental methods of machine elements research. Introduction to the various forms of machine elements laboratory testing (review and description of methods, devices and means of measurement and data acquisition). Laboratory exercises in the field of selected topics in machine elements investigation. Consultation in the preparation of the seminar work. Considered machine parts and elements are obtained by conventional manufacturing and processing technologies, as well as by additive production technologies.

Attendance requirement
