Reduction of Valvetrain Mechanical Losses
Kučera, Pavel ; Píštěk, Václav (referee) ; Novotný, Pavel (advisor)
The topic of this thesis is the mechanical losses in the valvetrain. The purpose is to describe the creation of individual losses and their possible reduction. The main factor of creation of losses is friction. The result of this thesis is to highlight the possible methods to reduce friction and other influences acting on the valvetrain. The main benefit is description various types of surface and design modifications of valvetrains, which are already used or are in development.

Modeling of DC motor in MATLAB/Simulink
Kunovský, Martin ; Kerlin,, Tomáš (referee) ; Hubík, Vladimír (advisor)
This bachelor’s thesis deals with the direct current motors, their properties and modelling. For modelling mathematic modul of direct current motor was created, which is linked to H-bridge and managed of PWM signal. After that general user environment GUI was created, which can run simulation after setting primary motor characteristic, and we can monitor it. This is executed in environment Matlab&simulink.

Produstion of internal wheel, by solid forming
Šimon, Miroslav ; Novotný, Karel (referee) ; Kopřiva, Miloslav (advisor)
The point of this work is bookish concept of the best technology of processing named component by solid forming. This work includes study, which is the clue to solutions. Another important topic is the global technological plan of component production from gear blank to product. It seems the best choice is die forging on forging press at three steps. Economically, die forging made by described method is the best.
