Highway bridge over wide wally
Mertová, Eliška ; Smejkal, Ing David (referee) ; Klusáček, Ladislav (advisor)
The aim of this diploma thesis was the design of three possible variants, how to span the wide and deep valley with a bridge. After an evaluation, situation of the highway on the only wide load-bearing structure which is constituted by a box girder with transverse cantilevers supported by prefabricated bar braces, was chosen as an optimal solving. The load- bearing structure made of post- tensioned concrete is going to be incrementally launched and be supported by one-column pillars along an axis of the motorway. The work is composed of a detailed design of this preferred variant, which is processed according to the ultimate and serviceability limit state including the construction stage analysis of the bridge by the construction technology by an incremental launching method.

Design of hillside elevator
Jaroš, Tomáš ; Smejkal, David (referee) ; Dvořáček, Jiří (advisor)
This Bachelor´s Thesis presents a structural proposal of a hillside elevator to a house on the slope used to carry goods and people. The elevator is designed in a total length of 40 meters with a capacity of 400 kilograms and slope of 25 degrees. The main focus aims at the drive of the machine and its safety. The elevator fulfills prescribed safety terms according to the 127/2004 directive. A 3D model of the elevator, a design drawing and drawings of its individual components are included.

Conceptual design of dosing system for sand
Jíša, Martin ; Omasta, Milan (referee) ; Smejkal, David (advisor)
This bachelor thesis is focused on conceptual design of a dosing system for sand in railway use. At the beginning after the introduction into the problematics, there is adetailed research of competitive devices currently on the market followed by a detailed analysis of their functions. Summary of all requirements (functional and technological) is made. Mechanical design of the current doser and two new design alternations are made. Those alternations are chosen to be the optimal solution for the new doser.

Design of hydraulic travel of reaper`s drive unit
Smejkal, David ; Hutař, Pavel (referee) ; Brandejs, Jan (advisor)
This diploma thesis deals with a design of hydraulic reaper’s drive unit and continual realization of its real prototype. The unit is designed with freelance wheel drive, continual change of speed and direction. A part of a drive unit is a remote control, which is primarily used for control of movement and mowing. On the base of research analysis the conception design was created, which has to fulfill all the needed requirements for build of prototype and its subsequent testing. Engineering design was performed in Autodesk Inventor 2012. Realized prototype was built by sponsor company. The components were chosen with regard to their functionality, quality and cost.

Reconstruktion of shock absorber test rig
Smejkal, David ; Strecker, Zbyněk (referee) ; Mazůrek, Ivan (advisor)
This bachelor thesis is focused on the reconstruction of shock absorber test rig which is placed in the laboratory of Machine and Industrial Design. The introduction deals with the basic description of particular dampers. There are also analyzed the dismantling and non-dismantling testers that serve for testing of dampers. Several special testers and testing devices are listed in this paper. There is a thorough division and description of dismantling testers. In the following chapters are mentioned various kinds of software used in the testing device for simulation of operating conditions. A special attention has been paid to the analysis of the function of hydraulic servo valve. The last chapter of this part is devoted to the description of the existing tester at UK and the advantages of a hydraulic tester comparing to the mechanical one. In the practical part of my Bachelor work are suggested several reconstruction options of the above mentioned tester. Subsequently the alternations that best meet requirements of simplicity and cost-effectiveness are chosen.

Design of Device for Regrinding of Specimens
Matečka, Martin ; Nečas, David (referee) ; Smejkal, David (advisor)
This bachelor thesis is focused on design of device for regrinding of specimens. In the first part is described grinding technology, cutting conditions for grinding of outer cylindrical surfaces and kinematic and dynamic phenomena arising in these conditions. There are also analyzed the grinding tools and their using. In the next points are described the designs of the grinder’s basic components. The last in this chapter is described the testing device on which the specimens are tested. The next chapter is focused on description of the objectives and analyzing the problems. There are described the variants of design solutions. After assessment of advantages and disadvantages of all variants is selected optimum design solution which is detailed described in the last section.

Residential Minicaravan
Bartošík, Jan ; Smejkal, David (referee) ; Brandejs, Jan (advisor)
The aim of this bachelor thesis is the design and construction of a small habitable caravan for two people. It is designed to be used exclusively in summer months. Thanks to the design and manufacturing, the caravan should offer sufficient comfort for short trips. The caravan has adequate sleeping space for two people, storage space and a kitchen with basic appliances. The gross-caravan weight mustn’t exceed 750 kg, so that a person with a driving license type “B” can operate it. The caravan frame is made of steel and wooden profile, the outer layer is made of aluminium sheet and the inner cladding of plywood. The whole frame is installed on a serial made chassis of the ALUX-27 trailers from Agados. The thesis will contain a possible construction design, draft and drawings.

OpenGL Application in Qt Framework
Smejkal, Dávid ; Láník, Aleš (referee) ; Navrátil, Jan (advisor)
There are described Qt, OpenGL and their mutual interconnection in the first chapter of the thesis. Especially, OpenGL techniques implemented in the program are closely specified. Qt toolkit is compared to three other multiplatform toolkits (AWT/Swing, QTK+ and wxWidgets). The second, more practical chapter of the thesis, includes program specifications, program design and program implementation. There are presented results and possible future development at the end of the thesis.
