Subject aims expressed by acquired skills and competences
The aim of the subject is parctical managing of mechanical quantities measurement methods. Students will be able correctly use a type of measurement equipment in accordance with the type of the problem.They will be able to carry out common vibration and noise measurements and will be acquainted with the principle and purpose of some more complex diagnostic methods - operational deflection shapes measurement, experimental and operational modal analysis.
