Involve the students in research methodology by application of experimental methods. Introduce PhD students with the types, application procedure and with data processing of laboratory and exploitation testing of machine systems structures. To trained them in preparation and caring out of experiments and in using of experimental data.

After successful completion of this course, the PhD student is qualified to perform experiments in the context of research projects and working on own dissertation aimed to be qualified for: 1. Measurement of physical quantities in solid structures (deformation, stress, loading, ...); 2. Planning and performing of experiments on mechanical systems in operation; 3. Laboratory testing of components of mechanical systems to the failure; 4. Laboratory testings of operating effects of mechanical systems (vibration, noise, reliability,...); 5. The statistical processing of test results and display of test results.

Introduction: The role of experimental results in comparing with analytical and numerical ones. Method of physical values measurement in solid structures (deformation, stress, load …). Methods of machine systems testing in service conditions (preparation, organization and carrying out of experiments). Laboratory testing methods without machine parts failures. Testing methods to the failure (fatigue testing of models and real machine components – examples and characteristics). Statistical processing of fatigue testing results. Testing of machine components reliability. Vibration and noise testing of machine systems components. Frequency analysis of vibration and noise measured results. Diagnosis of conditions in machine systems.

Work in laboratory. Testing process preparation and testing realization. Experimental results processing. Seminar work processing. Defense of seminar work.

no specific conditions

Laboratory for gears and gear transmission units. Laboratory for vibration and noise of machine systems components.
