NVH parameter determinantion of plate
Bouchner, Michal ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
The aim of this thesis is examination and verification of numeric model for solving acoustics and vibration problems. Specifically, we are speaking about cast iron plate machined from gearbox. Main objectives of this work is set of experimental and numerical analysis at this simplified part with follow-up numerical model, where same analyses examining not only structure, but especially acoustic space around were performed. Due to this we were able to compare data between experimental and numerical analyses and to be able to prove or disprove functionality and limitation of numerical model.

Design Concept for Noise Reduction at the Turbocharger Inlet
Surovec, Jindřich ; Vacula, Jiří (referee) ; Novotný, Pavel (advisor)
This work deals with the design of measures of noise reduction at the entrance to the TCR 16 turbocharger from PBS Turbo s.r.o. The solution is based on harmonic acoustic analysis using the finite element method of the Ansys program, where this method first determines the transmission losses of the existing configuration and then compares the two design solutions with the original configuration. In this way, it is determined whether the benefit of the design measure is sufficient.
