Noise Reduction Methods in Automotive Design
Kubica, Petr ; Janoušek, Michal (referee) ; Prokop, Aleš (advisor)
The aim of this bachelor thesis is create a research study about noise reduction methods in automotive design. The introduction of this work deals with acoustic and the influence of noise on people. Furthermore it deals with ways of noise creation in a car and its suppression. In the end of this work there is a valorization of certain methods at noise suppression of a personal vehicle.

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 of low-voltage supply and reference block based on the bandgap reference
Mudroch, Michal ; Kledrowetz, Vilém (referee) ; Prokop, Roman (advisor)
In this diploma thesis there is elaborated design of low-voltage power supply block using I3T25 technology. The theoretical part describes the basic structures used in the design, using CMOS and bipolar devices. Furthermore, the properties and the analysis used in the evaluation are described. In the design part there is an elaborated design of individual parts, including voltage references, current references, DAC converter, operational amplifier. In the last part, the power supply block is subjected to simulations for verification of temperature compensated output variables and analyzed circuit functionality.

Optimization of Methods for Manufacturing Wormshafts
Černý, Michal ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
The subject of this diploma thesis is the optimization of the production wormshaft under specific conditions in a particular company. The optimization was requested by firm as a solution in the areas which are defined by content of this thesis. In first part, the technology of the product manufacture is evaluated. Next analysis of the original production technology is performed the regarding rationalization explained later, proposing a new form of manufacturing process. In the following parts layout variants of workplaces are assembled. These variants are based on the newly designed technology. The final part presents a control jig, which will be used in quality assurance and manufacturing workplaces and allows to measure various type of wormshaft parts. In the discussion section there is a proposal of another possible solution for manufacturing optimization these key components that make up assembly control gearbox of valves and ball valves.

Rocker for Formula Student Vehicle
Šprta, Petr ; Prokop, Aleš (referee) ; Janoušek, Michal (advisor)
This thesis deals with a prototype of the rear suspension rockers of the racing monopost Dragon 10th generation, which is being developed at the Brno University of Technology within the international educational project Formula Student. Based on the research, the technology method of casting has been chosen for this purpose. The input for the prototype of the rocker arms is based on the impacting forces and suspension points given by kinematics of the vehicle. Based on these facts, topology optimization of the shapes has been conducted and the components have been modelled accordingly. Followingly, optimization focused on minimizing weight, deformation and stress were conducted using the reverse loading of modelled components. The last part of this thesis is concerned in the comparison of rear rockers of the last year‘s monopost Dragon 9. Taking into consideration the change of the concept, the mechanical properties of rockers are slightly better.
