Process optimalization and lean implementation in the manufacturing company ADC Czech Republic s.r.o
Mauer, Jindřich ; Obdržálek, Radim (referee) ; Strejček, Jan (advisor)
This Master's thesis deals with the optimilization of the production process of the firm ADC Czech Republic s.r.o. The first part the tesiis focused on the research study of the issue, which is used in the practical part. The second one is devoted to brief introduction of the company ADD Czech Republic and the introduction of the product, that is engineered on the production line. The next chapter is divided into three parts. The first chapter creates an analysis of actual condition. The second deals with the implementation of the proposial. Finally, the third part is focused on other possible proposals, which have not been properly worked out

Powertrain of unconvential V-6 diesel engine with balancing shaft
Vaculík, Tomáš ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
The aim of this thesis is to design a powertrain of unconvential V-6 diesel engine with balancing shift with angel of cylinders’s axis 90 degrees and crank pin ofset of 30 degrees. The thesis provides an analysis of balance of inertial forces and their moments, layout of counterbalances on crankshaft and balancing shaft. It also provides a layout of discrete model of torsional cranksaft mechanism and layout of rubber damper of torsional oscillations.

Design of linear axis for heavy machine tool
Göbel, Lukáš ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
The content of this thesis is the description the various component of the linear feed axis, which are used in heavy duty machine tools. This describes their features, advantages and disadvantages and on these basics, are selected different appropriate design variants. In the second part of this thesis has been drawn up constructional design of these variants. They were subsequently compared and then was chosen the most ideal one for the designed machine, which is heavy machine tool upper gantry type. The work also includes the 3D CAD model of the final version and drawing documentation.

Balancing of hydraulic machines
Buben, Marek ; Soukup, Lubomír (referee) ; Nováková, Naděžda (advisor)
This bachelor’s thesis is technical research dealing with issues of static and dynamic balancing of rotors. The first part of this work is devoted to explaining basic concepts associated with problems of balancing. As for the next part, this work defines types of imbalances and basic methods of balancing. The last part is devoted to describing machines for static and dynamic balancing and their operation in practice.

Two-cylinder motorcycle engine
Bolcek, Adam ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
The main aim of this master’s thesis is balancing of the inertia forces of sliding parts of the twin cylinder motorcycle’s engine by dummy connecting rod. There is description of two computing stances to design dummy connecting rod. Then there is comparison of these computing stances. The dummy connecting rod is designed and the strength analysis is done by FEM method (finite element method) to limit the state of material fatigue. Furthermore, a crankshaft is designed while considering rotation parts’ inertia forces balancing. Finally, a strength analysis by FEM method is done to limit state of material fatigue of the crankshaft

Two-cylinder four stroke spark ignition flat engine
Dragoun, Jan ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
This thesis deals with the possibilities for realization of the crankshaft-cylinder four-stroke gasoline engine is flat, usable in the urban vehicle. In the work described stresses exerted on the crank mechanism can balance the crankshaft, torsional stress and strength calculation method of control. In the final part of this work is outlined proposal for implementation of the crankshaft.

Powertrain of unconvential V-6 diesel engine with viscous type damper
Hejda, Tomáš ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
The purpose of this thesis is design an unconventional powertrain V-6 engine with cylinder opening lines offset 90 degrees and 30 degrees of crank pin offset. It is an analysis of the balance of the crank mechanism, proposed unbalance, build a model of discrete torsion system, design of viscous torsional vibration damper, compares the results of the calculation of strength without crankshaft damper and with damper.

Monitoring the impact of ultrasonic energy to the leveling of thick film pastes
Pokluda, Tomáš ; Buršík, Martin (referee) ; Řezníček, Michal (advisor)
This bachelor thesis is focused on the problem of levelling of a profile by ultrasound after printing thick layer pastes and on electrical resistance and geometrical dimensions changes. It describes a creation of hybrid integrated circuits, thick film technology and the screen printing method. It also includes basics of fluid physics, basics of fluid rheology, and description of principles of the used ultrasound transducer. Records of the levelling measurements are presented through the use of photographs, comments, tables and graphs.
