Laser brazing in the car industry
Podstavek, Michal ; Mrňa, Libor (referee) ; Kubíček, Jaroslav (advisor)
The project elaborated in frame of engineering studies of the subject M-STG Mechanical Engineering describes elementary methods of joining in the automotive industry. Moreover, it inquires into optimization of laser brazing on the back cover ŠKODA Superb. During the optimization of the process six samples were designed, and the adjustment of the brazing parameters were performed. Consequently, the samples were evaluated by tensile and metallographic tests. Finally, EDS analysis was performed and visual assessment as well.

Extrication of Persons Trapped in Crashed Vehicles with Respect to their Construction
Pirner, Adam ; Kupka, Petr (referee) ; Vémola, Aleš (advisor)
This thesis deals with the topic of extrication of people trapped incrashed vehicles regarding the construction of the vehicle. Part of the resources needed for this theses was taken from a literary survey drawn up with the help of the Research and scientific library in Hradec Králové according to the given topic and key phrases. The first part of the thesis deals with specific parts of the constructions of cars. This part is followed by description of road accidents, various kinds of accidents and possible deformations of cars after accidents. The thesis deals with extrication itself made by fire brigades, suitable procedures, kinds of interventions and means of used technical equipment. Another part suggests ways of saving trails and evidence during road accident interventions. Final part of the thesis is focused on overall analysis of the given problem based on personal experience, suggestions, negative aspects of the current situation and differences in training of possible situations with reality at the site of the accident.

Production single parts from sheet metal with usage technology deep drawing
Jurča, Jan ; Dvořák, Milan (referee) ; Žák, Ladislav (advisor)
JURČA Jan: The manufacturing of sheet metal part by deep draw technology. Thesis of Master´s Studies, the 5th Year of Study, the School-year 2008/2009, The Institute of Manufacturing Technology, Department of Machining, FSI VUT Brno.The thesis deals with the project of manufacturing the part of the car body – the fifth door by deep draw technology. The material is zinc-coated sheet metal HX220YD EN 10292. Mechanical properties and suitability of the material are evaluated by mechanical tests. The structure of the material is evaluated by metalography scratch pattern. The analysis of draw process and manufacturability of the part is made by calculations and AutoForm software. The production line, necessary machinery and construction solution of draw tool for the manufacturing the part are determined. Last section deals with economical evaluation of the production.

Mitsuoka Kit Car Design
Kratochvíl, Jaroslav ; Zdařil, Zdeněk (referee) ; John, David (referee) ; Pelikán, František (referee) ; Zvonek, Miroslav (advisor)
A dissertation deals with small single-placed car body design (so-called microcar cathegory). The new design is based on the undercart and the engine of serial Mitsuoka Kit Car. Therefore the aim belongs to re-design tasks. Analytical part of the dissertation deals with two basic questions influencing the final draft. The Corporate identity at first and a problematic of the target group level of aesthetical perception linked to preferred design. On grounds of analysis the core values for new design have been set down. The particular values have been presented with the help of existing reference objects from the field of automotive design. This part also includes a questionnairy, which had been focused on prefered design conception. Due to low microcars topic awareness in Czech Republic, the questionnairy had informational character and the final design conception has been chosen on the base of functional aspects analysis. The final design development, shown on sketches and basic software renderings, is based on gradual steps that lead to the core values expression with regards to input parameters and basic design rules as well. The final design is introduced together with description of its technical solution and detailed design. The solution respects the mentioned target group and the institution Corporate Identity.
