Simulation of commercial vehicle dynamics
Jobánek, Vojtěch ; Zháňal, Lubor (referee) ; Fojtášek, Jan (advisor)
It is possible to transport shipments for long distances due to trucks. Truck producers focus on operations efficiency with increasing transport demand. The thesis deals with simulation of drive. Particular possibilities of chassis construction are described in the recherche, on its base initial. Values for the simulation are chosen. The dynamic tests, which were afterwards evaluated, were carried on the model of the set.

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.

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.

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.

Evaluating the Need for Truck Centres on the D1 Motorway between Prague and Brno
Spáčil, Tomáš ; Kudláček, Jaroslav (referee) ; Libertín, Josef (advisor)
This diploma thesis deals with a design of truck-centres count and location near the motorway D1. This design is a result of aspects which can influent truck-centres‘ count, size and location. There are derived the aspects on the basis of calculation of freight transport intensity till the year 2030 and its concurrence to accident frequency, traffic flow regulation, and also its concurrence to management of personnel labour (AETR), means of eventual maintenance need and means of vehicles’ reparation, services for motorway attendants and finally its concurrence to possibilities of controls by public authorities and police. In order to regulate freight transport traffic flows is calculated size of parking spaces and suggested their appropriate locations.

Case studies quantifying property damage through no fault of the carrier after a car accident
Svozil, Milan
The injured party is entitled to compensation for the overall financial damage which has been caused due to accidental traffic accident. Škoda presents any loss of property. This is not only true for the damage (the amount by which the value of assets decreased), but also lost profits. The injured party must realize all the damage and property losses to him in a traffic accident occurred and must be quantified and demonstrated. These damages are liquidated liability insurance of motor vehicles participant who caused the accident. In most cases, the injured party seeks, and consequently they are satisfied only with compensation for damage to the vehicle, where appropriate, the costs of recovering and towing the vehicle to the nearest workshop. Further compensation, arising from accidental traffic accident has damaged usually required, although these damages are often many times higher. For a complete liquidation of such damages no unified methodology and for this reason there is a problem situations in their quantification. Problem situations that may occur in the quantification of property damage carriers are addressed in the paper by illustrative case studies and presents a complete procedure for quantifying the overall carrier of property damage that may occur as a result of total damage to the trailer and damage to cargo carried.

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.

The Study of the Parking Area on the Motorway D1
Šťastný, Radek ; Hornýš, Michal (referee) ; Radimský, Michal (advisor)
The task of my diploma work is the study of the parking area on the motorway D1 near Vyškov. This place will be connected with the motorway D1 between the present exit Vyškov – West (226) and Vyškov – East (230/1) in the direction to Kroměříž. The parking area (the parking place, the petrol station, the restaurant) and the truckpark will be designed with the reason of the high intensity of cars and lorries on the motorway D1 and with the reason of the lack of the parking places for the lorries.
