Numerical Modelling of the Gear Mesh Stiffness
Gazda, Silvester ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
This master's thesis deals with the design of FEM model of gear pair with an intention to find out how stiffness changes during meshing. It firstly describes the necessary knowledge needed to analyse the problem, like the geometry of an involute tooth and evaluation of meshing stiffness. Followed by a description of work procedures from the creation of models through settings of mesh, contacts and analysis to evaluating of results.

Measurement of complicated shape parts using image processing
Sujová, Sára ; Březina, Michal (referee) ; Štětina, Josef (advisor)
The bachelor's thesis deals with the topic of wear measurement of the pinion gear of the REA actuator used in the regulation of the turbocharger wastegate system. The first theoretical part of the thesis describes the topics of wastegates, actuators, gears and optical methods. In the second part, a pinion measurement method is implemented using a digital microscope and an application to measure the width of the pinion tooth thickness designed in the MATLAB environment.

Design of production technology for a pinion shaft of a gearbox
Hulvej, Matúš ; Slaný, Martin (referee) ; Zemčík, Oskar (advisor)
The diploma thesis presents a design of a technical project: design of production technology for a pinion shaft of a gearbox and design of alternative technology. It focuses on the analysis of a component, the selection of materials, machines and tools, and the creation of a manufacturing drawing and technological process of the production. It is concluded by a technical-economic evaluation, based on which are both designs compared and evaluated which design is better for specific conditions.

NVH Analysis of Transmissions
Gazda, Silvester ; Zubík, Martin (referee) ; Prokop, Aleš (advisor)
This bachelor's thesis deals with the design of measuring noise and vibration of vehicle transmissions. First describes the main parts of the transmission. This is followed by a description of sources of vibration and noise, and their travel. Significant work is devoted to analysis of the frequency spectrum, of its creation and evaluation. It also includes a description of the measurement and the necessary equipment, along with a description of the basic principles of its functioning.

Computational Models of Transmission Dynamics
Czakó, Alexander ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
This bachelor thesis deals with a summary of knowledge about the computational models of transmission dynamics. Dynamics modelling has different levels of complexity. From the modal, harmonic analysis solved in the FEM, up to creating a virtual prototype in the MBS softwares. In the introduction, there are presented the basics of analytical dynamics and mechanical oscillation which are the basis of individual analysis. Vibration sources in transmission are described as well.

Car Front Axle Driveline Gearbox
Černuško, Lukáš ; Černý, Jiří (referee) ; Kaplan, Zdeněk (advisor)
Goal of the Master Thesis was to design conception of electric vehicle driveline, which is able of torque vectoring between each wheel independently and to design front axle gearbox. The aim was to use up the car on race track and to test dynamic properties of electric vehicle for follow-up development. Due to determined requirements and possible solutions the conception of driveline was designed and basic parameters were defined. The main part of the thesis contains a design of gearbox including strength calculation of gearing, the control of shafts to fatigue and elasticity limiting states, life of selected bearings. Gearbox case was subjected to FEM analysis. The last chapter uses simulation to gain vehicle acceleration. Designed electric driveline is applicable to other sport vehicles after some modifications.
