EV-55 aircraft modification for water level landing
Šponer, Jan ; Vaněk, František (referee) ; Chybík, Ladislav (advisor)
Diplomová práce se zabývá modifikací stávající pozemní verze letounu EV-55 pro možnost přistání na vodní hladině. Snahou je najít takovou variantu, která nepovede k výrazným konstrukčním zásahům do draku letounu a bude vyhovovat stavebnímu předpisu CS 23, zejména požadavkům týkající se plovatelnosti a stability na vodě. Je proveden hmotový rozbor modifikované verze a s tím související omezení hmotové obálky a rozsahu centráží. Zatížení od vody je spočítáno v souladu s CS 23. Pro toto zatížení je následně navrhnuto konstrukční řešení uchycení plováků k trupu a provedena pevnostní kontrola jednotlivých prvků a spojovacích uzlů. Tyto hodnoty jsou dále porovnány s pozemními případy zatížení a stanoveny součinitele rezerv. V závěru jsou spočítány letové výkony: maximální horizontální rychlost, stoupavost, dolet a vytrvalost.

MR Strut of Steward Platform for Vibration and Shock Isolation
Macháček, Ondřej ; Šindelář, Martin (referee) ; Mazůrek, Ivan (advisor)
The thesis deals with design magnetorheological strut of vibration isolation adapter for cosmonautics. For its optimization is necessary to create several virtual models. The dynamic model of the mechanism - the Stewart platform, rheological model for determining the damping force of MR damper and model of the magnetic circuit to guarantee the required intensity in the gap. These models, along with controls models that are primarily concerned with strength calculations, will help with design. Designing using virtual models requires constant monitoring and verification. It is a rather broad topic including eliminate vibration also kinematics, dynamics, hydraulics, pneumatics and last but not least electronics and magnetism. It is necessary to communicate with experts in their field and use their knowledge and experience to create, but also to control of the individual models. The thesis was created in cooperation with Honeywell Aerospace Division (ESA).

Multipurpose load-bearing timber hall structure
Matuška, Martin ; Sýkora, Karel (referee) ; Straka, Bohumil (advisor)
This Master’s thesis is focused on the design and structural analysis of load-bearing structure of a multipurpose hall that is strained by the permanent load, working load and climatic load. The hall has the shape of an elliptical dome. Maximum margin of the structure is 60,0m and maximum height is 18,0m. Main carrier elements of the structure are radially arranged curved beams made of glued laminated timber, class SA(GL24).

Measurement of the length and volume stiffness of steel bellows
Valík, Michal ; Roupec, Jakub (referee) ; Mazůrek, Ivan (advisor)
This bachelor’s thesis deals with the experimental measurement of the length and volumetric stiffness of steel bellows. The first part is dedicated to the analysis of the utilisation of metal bellows connected to the mentioned theme. This part also deals with the actual knowledge of metal bellow’s stiffness characteristics. The second part contains descriptions of selected methods of the measurement process. The last part of this work focuses on the evaluation and analysis of measured data in order to gain the results of the length and volumetric stiffness of metal bellows.

Steel structure of swimming pool roof
Krchnák, Martin ; Barnat, Jan (referee) ; Štrba, Michal (advisor)
This bachelor thesis describes the design and assessment of steel structure of the swimming pool roof. The supporting structure of hall has 40.00 meters span, 50.00 m length and 10.53 m height. Main construction material is steel, grade S355 and S235. There were compared 2 possible variants of the roofing, and one of them was calculated in detail. There is developed a static analysis of the main load-bearing parts of the structure, including joints and selected details. The supporting structure of roofing consists of the polygonal wrapped lattice structure made of steel circular in the transverse direction.

The Roofing of Terraces of a Stadium
Bartoň, Radek ; Sýkora, Karel (referee) ; Puchner, Josef (advisor)
My task was to propose and consider steel structure of roofing of a terraces on an athletic stadium. Terraces, with the ground-plan dimensions 12,0 x 80,0 m, are designed as a reinforced concrete structure and its structural analysis is not included in this thesis. Construction is situated in area of Rožnov pod Radhoštěm, which meant, It had to be accounted with considerable variable loads (wind, snow), which is associated with enlargement of a cross-sections. Cross sections of the main elements were proposed and considered and also selected joints and details of the structure. Assigned drawings are included in attachments of the thesis.
