Active Damping of Machine Tool Head
Škúci, Michal ; Marek, Jiří (referee) ; Březina, Tomáš (advisor)
The master’s thesis deals with building mechatronics model of machine tool head delivered by company TOSHULIN,a.s. for purpose of damping vibration. Mechanical part of the model is based on modeling of system of flexible bodies. Components are modeled in FEM program ANSYS and subsequently reduced using Craig-Bampton method. The system of flexible bo-dies is created in MBS program ADAMS. Model is linearized and subsequently reduced. As a element of active damping is used linearized model of magnetic bearing. For control is desig-ned PID controller. The comparison of damped and undamped model is conducted in the end.

Passive compensation of a thermal deformation for a machine tool
Šabart, Adam ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
This master thesis deals with passive compensation of a thermal deformation for a binder of portal machining center. The problem is solved by computational modeling with finite element method using ANSYS Workbench software. Afterwards mathematical optimization (also using ANSYS Workbench software) is used for finding binder parameters in order to reduce thermal deformation and its weight. The output is two new versions of binder which are compared to the original configuration.

Cultural Center in Koprivnice
Kocián, Václav ; Marek, Jiří (referee) ; Nový, Vítězslav (advisor)
The project is to design the reconstruction Koprivnica's center building cultural center and museum of Tatra, which was built in 1991. Of the building is located between the street and Záhumenní Koprivnická flow of the river, which at this point is hidden in the length of 150 meters and produces along with height dominates the Hotel Tatra quite complicated urban situation. Proposed reconstruction allows for the transfer of the Tatra Museum in its factory premises and complete cleaning KDK building to its original mass. The resulting space is designed single-storey building with commercial use of the space in creating a semi-enclosed rekonstruavanému cultural house.

Design of headstock for boring centre
Raszka, Pavel ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
The bachelor´s thesis deals with the design of the headstock for the horizontal boring center. In the first part of the thesis, a search is made in the field of boring machines and main parts of boring machine headstock. Based on this theoretical analysis, the input parameters for the calculation of the tension, power and torque characteristics of the headstock are selected. Subsequently, the design of the headstock is done using a 3D model.

Gallery aviation technology and traditions of aviation at the airport Medlánky in Brno
Kašpárek, Michal ; Marek, Jiří (referee) ; Šindlar, Jiljí (advisor)
The theme of Master thesis is a Gallery of aviation technology and traditions of aviation at the airport Gallery aviation technology and traditions of aviation at the airport Medlánky in Brno. The project insludes overall operation of the sports airport, then deal in detail operations of the museum and related services within the airport. The new campus will humbly entered in the countryside, in an attractive location Medláneckých hills creates another attractive feature and despite the complex operation and movement techniques does not create a barrier to the contrary territory it unites and is a natural center. Airports Medlanky was founded already in the twenties of the last century, and since then the area is relatively non-conceptually grew by more hangars and various outbuildings. Of these, only two were preserved original wooden sheds, which adds yet another new administrative and ceremonial buildings. Operational buildings set limits on technology, the new representative building it closes, and defining a space for people, nature trail connects the area, offers wonderful views and creates a public space that makes passers airport. The whole area is oriented to the back area and opens onto the landscape, wide area thus presents an iconic silhouette reperzentační building. The curve of the building provides space aircraft-makers to fly and allows collision-free movement of people and equipment around the airport and also generates a dignified space for aircraft to fly longer will. Exposure air museum at the second floor of the building and the visitor thus rises to individual gliders that levitate in space, the sun's rays make their reflections on the polished bonnets and backgrounds are vivid airports and skies. The museum offers a walk through the history of aviation in a different context than conventional hangars. The entire building is representative functionally and structurally divided into three parts. The ground floor closer to the a

Active Compensation of Tool Deflection
Zarboch, Jaromír ; Marek, Jiří (referee) ; Březina, Tomáš (advisor)
This paper deals with design of tool deflection compensation system for milling spindle C1, provided by company TOSHULIN, a.s. A simplified simulation model of the spindle supplemented by compensatory elements was built by using programs ANSYS, MD ADAMS, Matlab/Simulink. As action elements there were use three piezoactuators each controled by PID controler. Efficiency of this compensation system was verified based on performed simulations.

The GPU Accelerated Optimisation of the Water Management Systems
Marek, Jan ; Petrlík, Jiří (referee) ; Jaroš, Jiří (advisor)
Subject of this thesis is optimalization of storage function of water management system. The work is based on dissertation thesis of Ing. Pavel Menšík Ph.D. Automatization of storage function of water management system. As optimalization method was chosen diferential evolution. Sequential version of the method will be implemented as a first step, followed by CPU accelerated and GPU accelerated versions.
