Measurement and Evaluation Methods of Powertrain Vibrations
Vítek, Michal ; Janoušek, Michal (referee) ; Prokop, Aleš (advisor)
This bachelor´s thesis deals with the methods of measurement and evaluation of powertrain vibrations. Introduction of this work is defining the basic parameters of vibration. It also shows the experimental modal analysis, vibration excitation methods and measuring responses to a given excitation. The last part is operational modal analysis and its comparison with experimental modal analysis.

Modal analysis experimental method verification
Pop, Miroslav ; Lošák, Petr (referee) ; Houfek, Martin (advisor)
This diploma thesis deals with the issue of operational modal analysis, which is one of the newer areas of structural dynamics that makes it possible to estimate modal properties of structures directly during their operation. The aim of this work is to create theoretical basis of operational modal analysis, more specifically of Frequeny Domain Decomposition method. Furthermore, apply this method to a selected structure and verify the achieved results using computational modelling and experimental modal analysis. The technique of dividing the experiment to separate measurements using reference sensor was used. Evaluation of the operational modal analysis was performed using self-created function for the MATLAB software and using the commercial PULSE Operational Modal Analysis software. Obtained results were verified by computational modelling and experimental modal analysis.
