Design of universal belt grinder
Skala, Ondřej ; Kvarda, Daniel (referee) ; Valena, Martin (advisor)
This thesis focuses on the design of a universal belt grinder with the capability for both vertical and horizontal grinding, aiming to maximize its usage potential. Several grinding attachments have been designed for the grinder, with attention to high quality, versatility, and user-friendly operation. The theoretical part describes grinding, types of belt grinders, and abrasive belts. Based on the research, specific requirements for the belt grinder are established, and a suitable type of construction is selected from the conceptual solutions. This is followed by a design proposal supported by calculations necessary for the proper and reliable operation of the machine and stress analysis using the finite element method. The final part describes the manufacturing and assembly of the machine, concluding with the verification of the functionality of the entire belt grinder, including all grinding attachments. The result is a fully functional belt grinder that meets the specified requirements.

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.

Design of bench drill
Štěrba, Jakub ; Marek, Tomáš (referee) ; Pavlík, Jan (advisor)
The aim of the work is a bench drill structural design. The first part describes drilling machine categories, compares some of drill press machines available on the market and lists main flaws of most drilling machines on the market. In the second part the basic concept is selected and the actual design of the individual components of the drill is performed. The third part contains selected strength and kinematic calculations. In the last part, the final model of the machine is presented, and the current production progress is discussed.

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.

Design of the Shift Mechanism Dedicated for Electric Driven Cars
Capoušek, Josef ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
In this paper the problematic of the design of the shift mechanism for a multi-gear transmission is presented. Research part is focused on the recent electric drive units development and the application possibilities of multi-gear transmissions. Available studies shows a possible improvement in vehicle parameters, primarily a reduction in energy consumption and vehicle drive range. Design of the shift fork mechanism includes the conceptual design creation, the optimal variant choice based on a multi-criteria assessment, the structural design and the subsequent analysis of components and creation of a technical drawing of selected parts.

Three-Aisled Steel Building
Lečbych, Antonín ; Bajer, Miroslav (referee) ; Buchta, Stanislav (advisor)
The thesis contains the design and assessment of three-aisled steel building for small metal production. Supporting span of construction hall is 9, 18 and 9 m. In the middle wing is situated bridge crane with capacity of 2 tons. The estimated location of the object is Luhačovice. The initial design concept was specified by supervisor (as the idea of the investor/architect), for which was did static and structural solution and assembly details. For selected option was made a calculation of supporting structures and selected assembly details. The hall has a rectangular floor plan of 36x36m and ridge height is 9 m. The central wing is made of steel and side extensions are made of glued laminated timber.

Engineering design of the vehicle suspension rocker
Poláček, Vojtěch ; Ramík, Pavel (referee) ; Bradávka, Marek (advisor)
Diploma thesis deals with the design and stress analysis of the rocker suspension for an autocross car. The research describes some real cases of using suspension with pushrod and rocker in motorsport. Subsequently, the work deals with the design of the wheel bump/rebound limiting stops and bump/rebound measuring. The challenge is to design a component shape, size and select fit of a rocker with an emphasis on low weight whilst maintaining sufficient strength and rigidity. The design study include stress analysis which leads to optimize the final shape.

Design of the test facility
Pavluš, Martin ; Pavlík, Jan (referee) ; Tůma, Zdeněk (advisor)
The thesis deals with the design of automated testing equipment of selected types of pneumatic valves. The problem of manual control process is its inefficiency, both in terms of human error rate and time loss caused by further assembly. The automated manual inspection process eliminates the problem. In the theoretical part, the types of switchgear are described, selected measuring procedures and methods of measurement are described. In the practical part, the measuring procedure was set out and on the basis of it there were designed variants of the testing machine and test circuit. The conclusion of the thesis contains evaluation of the whole project.

Design of collector
Podhorský, Michal ; Létal, Tomáš (referee) ; Horsák, Libor (advisor)
The aim of this thesis is to make the design of the collector. The work is divided into two parts. The first part will analyze the individual parts of the collector and its analytical calculation using the EN 12 952, ČSN 69 0010 and ASME I. The second part is focuses on the verification of the analytical calculation using the FEM in ANSYS and explore the most dangerous places. The result is also creating drawings documentations.
