Learning outcomes of the course unit:
The main aim of this subject is to provide an introduction to the fundamental concepts of how to detect the reason and nature of the failures by the engineering diagnostics and mainly by the vibroacoustic signals. The subject presents condition monitoring of the machines, machinery and mechanical systems, which is useful at determined times interval between maintenances and at the security. As such, the subject should be of interest to students in engineering programs at the university level and to students in technology and technician programs at community colleges who need to acquire a basic understanding of engineering diagnostics and its applications in practice and mechatronic systems. The students will know more about European directives and legislative documents and standards about dynamic exhibition of machines, methodology of the measurement of vibration and noise, type and nature measurement, basic measuring system, microphone, sensors, multifunction analyser of vibration and noise, using the computers for signal analysis
 
Course contents:
The subject contains the methods of engineering diagnostics/condition monitoring machines, machinery and mechanical systems. Specifically: characteristics of acoustic vibration, levels, time signal, frequency spectrum, cepstrum, transmission of vibro-acoustic signal through surroundings, diagnostics model generating of vibro-acoustic signal, characteristics of signals and their transformation, reference frequency spectrum and reference mask, cepstral analysis, envelope analysis, speed frequency, severity vibration, detection of faults, condition and quality of the machines, sensing a analysis of vibro-acoustic signals, windows, sampling, filters, modal analysis, orbital analysis, detection of faults and reasons for different machines. Next the European directives and legislative documents and standards about condition monitoring of machines, methodology of the measurement of vibration and noise, type and nature measurement, basic measuring system, microphone, sensors, multifunction analyser of vibration and noise, using the computers for signal analysis, givens quantitative and qualitative criteria and their using at the machatronic systems.
