Virtual Prototypes of Drivelines
Janoušek, Michal ; Dundálek, Radim (referee) ; Slimařík,, Dušan (referee) ; Píštěk, Václav (advisor)
The thesis deals with computational modelling of heavy duty off-road vehicle driveline components. The thesis is divided to two main parts. The first part deals about modal analysis of selected driveline components. MBS computational study was performed based on modal analysis results. The second part of thesis deals with experimental verification of computational model. Pass-by noise and vibration measurement was performed. Measured signals were processed in frequency domain to find noise and vibration sources.

Shape Optimalisation of Aircraft Engine Crankshaft
Vopařil, Jan ; Drápal, Lubomír (referee) ; Novotný, Pavel (advisor)
This thesis describes the variety and the width of issues connected with crankshafts of combustion engines. It distinguishes different factors, which influence the shape and size of these crankshafts and the selected findings are then transferred into the design of crankshaft for the particular engine. The thesis also presents coherent description of application of topology optimization to the particular crankshaft and also different, more complex design procedures leading to the optimal shape of crankshaft are afterwards suggested. Quality of such a design is then verified by comparative analysis of fatigue of the crankshaft.

Mathematical Model of motor vehicle driving gear
Marek, Petr ; Laurinec, Marián (referee) ; Porteš, Petr (advisor)
The subject of my master’s thesis is creating a mathematical model of motor vehicle driving gear using the software programs MATLAB / Simulink. The results are presented via graphs of the data gained from the simulation of a car driving on a determined track. The parameters used in the model come from a specific file and they can be changed anytime in order to correspond with the particular vehicle.

Drivetrain of a 8x8 truck
Hebnar, Tomáš ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
This thesis is focused on building a replacement torsion system of drivetrain of 8x8 and 8x4 trucks and subsequent computational analyses of built systems. There were made two analyses. The first one is a computational analysis of the shapes of vibration and The second one is a sensitivity analysis. The sensitivity analysis is studying effect on the size of the natural frequencies under the effect of gear ratio.

Torque vectoring differential utilization in the design of the current automobiles
Marek, Martin ; Blaťák, Ondřej (referee) ; Porteš, Petr (advisor)
The object of this bachelor thesis is to create analysis of the structural design ”Torque Vectoring” differentials and powertrain vehicles which use this type of differential. The project outset is devoted to an explanation of what the differential is and how it works, and then the distribution of differentials. The next section deals with active differentials, their principle function and design solutions. The end of thesis includes design solutions powertrain some models of vehicles using active differentials. The thesis has the character of search and contains no calculations or custom designs.

Systems for performance flow distribution in vehicles powertrain
Novotný, Petr ; Suchý, Jan (referee) ; Fojtášek, Jan (advisor)
The bachelor thesis tries to provide compact knowledge about differential systems. In the first part of the thesis you can find information about basic function and differentials are divided into several groups. Second part describes elementary kinematic and torque quantities which have significant influence on the character of differential. Last part of my thesis is concerned with groups of differentials mentioned in the first chapter. Also in the last part there is place devoted intelligent differentials which are nowadays on a market.

Powertrain of five -cylinder gasoline radial engine
Vítek, David ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
This Diploma thesis deals with a design of a powertrain of fice-cylinder gasoline radial engine with assigned main parameters (bore, stroke, etc.). The work is divided into several parts: kinematics of the radial engine, creation of 3D models, force acting on the connecting rods, balancing of the engine. The last part is focused on creating MKP models, stress analysis and determining of fatigue safety of the selected parts.
