Development and weight reduction of central housing for commercial vehicles
Blecha, Martin ; Pittl, Michal (referee) ; Píštěk, Václav (advisor)
The theoretical part of the thesis is focused on the clarification of the central housing function and its placement in a truck. The central housing function and placement depend on a vehicle chassis design. There is the weight optimization of the housing which is solved in the practical part of the thesis. The optimization is based on strength calculations of the Finite Element Method. There are weight savings and financial savings evaluated at the end of the thesis.

Constructive technological project of block of flats in Strážnice
Rozumek, Jakub ; Kopecký, Lukáš (referee) ; Diaz, Yvetta (advisor)
The theme of my diploma thesis is Building and Technological Project for a residential building in Strážnice. This is a study of the implementation of major technological stages of object SO- 01 residential building, the project concerning the construction site installation, design the mechanical assembly, traffic solutions, technological process earthworks, foundation structures, piles CFA and reinforced concrete ceiling construction. The work includes further object schedule, financial plan, a detailed timetable for construction of residential building, the budget, the inspection and the test plan, safety hazards on a construction site in the implementation of the substructure object and thermal technical assessment of selected structures.

Optimization of parking spaces for buses and trucks
Bedřich, Marek ; Čepil, Jiří (referee) ; Radimský, Michal (advisor)
Main focus of diploma thesis is optimalization of dimensions stated in parking norm ČSN 73 6056 Parking areas for road vehicles. Goal of the thesis was to optimalize dimensions stated in norm from 2011, eventually come up with a new type of parking space. Thesis is based on recherche, which was done on both previous and actual Czech norms as well as on foreign norms. Change in dimension was possible due to evaluation of swept paths of the individual parking slots. New suggested dimensions are stated in the conclusion.

Moving object detection
Škuta, Pavel ; Petyovský, Petr (referee) ; Richter, Miloslav (advisor)
The aim of this these was devise a automatic system applications, monitoring entering of motors vechitles with in automaric collection of trafic data. Automatic system allows identify of mooving vechitlses in slow speed and searching of the area registration number. Theoretical analysis of possible kind solving problems detection moving vechitles and their localization. From possible solutions was selected solution by camera systems. Was take a pictures of vechitles, whitch is as true of the real scene. On the pictures was testing of algorithm for detecting of area registraction number of vechitles. Designed system is possible to use for automatic monitoring mooving entering vechitles.

Mechatronic Approach to Vehicle Dynamics
Kučera, Pavel ; Kaplan, Zdeněk (referee) ; Havlíček, Miroslav (referee) ; Píštěk, Václav (advisor)
This theses deals with mechatronic approach to a vehicle dynamics. It is divided into two main parts. There are prepared vibration analysis, measurement and analysis of functions of truck powertrain in the first part. The second part describes the creation of computational models allowing to simulate driving conditions, vibrations of the vehicle and its extension for the development of mechatronic systems. There are shown different driving modes to control created algorithm of mechatronic system. The main tool for the development of mechatronic systems is the created simulator of vehicle enabling testing of computational models in real time.

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.

Truck Cabin Suspension
Hradský, Martin ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
The diploma thesis, which belongs to the area of vehicle dynamics, deals with the issue of suspension of trucks cabins. In particular, it focuses on the suspension of a race truck cab such as the Rally Dakar. Includes an overview of truck suspension (especially cabs), driving comfort assessment methods and the impact of vibration on human. To verify the suitability of using different cab suspension concepts, a multibody model was built in program MSC ADAMS. Suitable primary suspension has been found appropriate for this model. Cab suspension was tested for driving safety, but first for driving comfort.

Trucks Mechatronic Systems
Černošek, Jiří ; Vopařil, Jan (referee) ; Kučera, Pavel (advisor)
Bachelor thesis deals with presents mechatronic systems, which are used in trucks. In the first part are described basic principles of mechatronic systems and components, of which they consist. The second part summarizes the most frequently used systems and describes some of them more in detail for their functional impact on vehicle properties. Third part explains the ways of modeling these systems together with their testing. In the last fourth part are stated the views to the future of mechatronic systems within the framework of autonomy.
