Use of modern manufacturing technologies for transmission components
Drapač, Jiří ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
The aim of this bachelor thesis is to evaluate the possibilities of application of alternative production technologies in the company Wikov MGI a. s. for the production of gearbox components. The review part of the thesis deals with additive technologies, which are Selective Laser Melting (SLM), Binder Jetting (BJ), Cold Spray (CS) and Wire Arc Additive Manufacturing (WAAM). For each method, the pre-production preparation, process with printing parameters and post-processing are described. In the next section, each technology is critically evaluated for applicability to gear components. From the results, the most appropriate application of the technology to one selected component is detected. In the practical part, optimization of dimensions and weight is performed by design modification of the selected component. On the basis of economic and technical calculations, a comparison between the current and the proposed manufacturing process is made.

Road bridge over a local stream
Vondráček, Jan ; Zich, Miloš (referee) ; Koláček, Jan (advisor)
The topic of this bachelor thesis is design of a road bridge across a valley with stream. For more detailed design was selected variant of one span cable-stayed bridge, from two variants of bridges with different static solutions which were created. Internal forces were determined by software SCIA Engineer 22.0. For analyse the structure were created three computational models – slab model, spatial bar model and slab-wall model. Structure was assessed for limit states according to currently valid standards.

Slab bridge
Malý, Jan ; Muroň, Vlastimil (referee) ; Panáček, Josef (advisor)
Bachelor's thesis deals with the design of a road bridge over the Volyňka river. Three bridging variants were proposed, of which the bridge variant, whose supporting structure consists of an additional pre-stressed concrete slab, was chosen for subsequent detailed assessment. The variation with prestressed prefabricated girders with composite slab is chosen for more detailed assessment. Detailed structural design is made and selected parts of the construction are checked for ultimate and serviceability limit state by Eurocode. Calculation of load is made by manual way and then by exact way with program Scia Engineer 22. The results from both calculation methods are then compared. Detailed drawings and visualization are made as well.

A design of manipulator for laser engraving device
Hanák, Jan ; Knoflíček, Radek (referee) ; Tůma, Jiří (advisor)
This thesis presents a research in the field of laser technologies used in industry and systems for laser marking of rotating parts. The output is a design of a laser cell that serves to mark rotating parts and that can be incorporated into an automated production line. The concept is developed in the form of a 3D model which is accompanied by necessary technical calculations and a justification of the choice of used components.

Garage with Fuel Station
Borkesz, Michael ; Pilgr, Milan (referee) ; Barnat, Jan (advisor)
Bachelor thesis presents the structural design of a load bearing steel structure of garage with roof construction of adjoining fuel station. The object is located in periphery area of Uherske Hradiste city, near Jarosov district. The ground plan dimensions are: 36 x 32 meters garage hall; 20 x 20 meters fuel station roofing. Heights of both construction tops are same – 10 meters above the surface. As the main material supporting elements was designed steel S355. The main supporting structure compose of trusses, which are hinged supported by columns. The roof deck is heat insulated, supported by purlins. The wall deck is simillar to roof deck, except of the front wall, which is partly composed of glass casing. At the both sides of garage hall are designed gates for vehicles. The roof deck of fuel station roof construction composes from one single trapezoidal sheet, also supported by purlins. The work contains structural design of individual elements, including mutual joints and anchoring. Calculations are performed according to standards of EN.

Car Showroom
Smrčka, Václav ; Buchta, Stanislav (referee) ; Bajer, Miroslav (advisor)
The aim of the thesis is to design and appreciation steel load-bearing structure of motor show. The object is situated in Brno. The Structure consist of tubes and rolling sections. The breadth of construction is 36,5m, lenght 42m and height in the heihest point is 13,2m. The structrure is consists of three parts. Show room, offices and workshop. The height of show room is 20m, offices 8,5m and workshop 8m. The show room consist of arched truss girder. The distance of each cross links is 6 m. Structural design were perfomered by Scia Engineer 2017 and hand computation.

Continuous box girder bridge over the valley
Haluška, Ľuboš ; Svadbík,, Petr (referee) ; Koláček, Jan (advisor)
The aim of this Diploma thesis is focused on a design of the road bridge between Brodzany and Partizanske municipality, spaned the Valley. The design is processed in three preliminary designs. Selected variant is a continuos girder box with inclined walls, post-tensioned by bonded cables. Structural analysis includes the influences of construction by TDA method. The sctructure is assessed for temporary and permanent states. Design and check were carried out according to EC.

The Multipurpose Centre in Olomouc
Toman, Tomáš ; Pilgr, Milan (referee) ; Šmak, Milan (advisor)
This diploma thesis deals with design of timber load-bearing structure of a Multi-functional object in Olomouc. This object has an eliptical ground plan with dimensions 50x30 metres and height of 11 metres. The idea of the shape is an eliptical dome. This dome was designed in two options, those are a Rib dome and a Föppel dome.

Box girder bridge
Vostal, Lukáš ; Pecha, Jakub (referee) ; Nečas, Radim (advisor)
The subject of this thesis is the design of a prestressed box girder construction with several spans. Two variants are designed and for detailed solving was chosen the variant of the box girder. The length of loadbearing structure is 212 m, the longest span has 60 m. The calculation of load effects is done by software Scia Engineer 19.1. Drawing part is done by software Allplan Engineering 2021. The thesis includes drawings, representation of the construction proces, visualization and a structural design. Designing and assessments were made according to currently valid European standarts.
