Numerical analysis of rubber bushing assembly
Novotný, Tomáš ; Rekem, Jakub (referee) ; Dlugoš, Jozef (advisor)
This diploma thesis deals with different approaches to the numerical simulation of the assembly of a chassis unit consisting of a rubber bushing, a stabilizer tube, a clamp and a fixture that simply represents the vehicle frame. The goal is to compare individual numerical simulations and find the most suitable methodology for this process. The first part of the thesis is devoted to the theory focused on the issue of nonlinearities in the finite element method. It provides important knowledge for the creation of the practical part. The second part contains the procedure for the design and creation of individual methods of numerical simulation of the assembly of chassis components. In the last part of the work, the results obtained from the individual simulations are evaluated, their mutual comparison and verification of the calculated data with a real experiment is carried out. Final recommendations were established based on the information obtained.

Manufacturing of mirrors clamp
Večeřa, Jaromír ; Jopek, Miroslav (referee) ; Podaný, Kamil (advisor)
This thesis presents a proposal for manufacturing of a mirror clamp, used for wall mounting. The clamp is made of stainless steel 1.4301 with a thickness of 1 mm. Manufacture series produces 40,000 pcs/year. After considering the individual manufacturing options, production in the combined process tool was chosen. The manufacture takes place in five steps, the utilization of the material is 84.1 %. This was completely proved by technological, design and control calculations. According to these calculations, a tool was designed with all of the technical documentation. Due to the forming force of 180 kN and the work of 113 kJ, the eccentric press T-30 CE from the company SanGiacomo Presse was chosen.

Special induction machine as source of electric energy
Dušek, Jiří ; Janda, Marcel (referee) ; Skalka, Miroslav (advisor)
This work deals with description of an induction machine principles for both of motor and generator operations. Then is been described a special kind of an induction generator working into an isolated system. The construction of an induction generator was designed with two stator winding connection due to possibility of the variable number of pole pairs. Also there is an excitation capacity design for self-excitation. Last part of this work contains the measurement of an induction generator with different values of excitation capacity and both terminal clamps connection.

Design and Production of Clamps for Mandrels ISO 40
Tomešek, Viktor ; Kalivoda, Milan (referee) ; Sedlák, Josef (advisor)
Main aim of this bachelor’s thesis is to design and product clamp for mandrel ISO 40. This clamp will replace the other one, which is used in the milling workshop C2 on BUT Faculty of Mechanical Engineering. It will ensure easier and faster operator’s work during tool change. Also manufacturing process, selected material and cutting conditions are described in this thesis. Theory necessary for an understanding of the issues is stated in introductory section. In the final part, there is executed technical-economical evaluation with the overall costings associated with the production of the clamp for mandrel.

Information Centre
Kovář, Jindřich ; Štrba,, Michal (referee) ; Barnat, Jan (advisor)
This bachelor thesis is concerned with the static project and the consideration of the carrier steel construction of the information centre that means the two-storeyed building with the 24 x 24m extent. The project is solved by two options. In both cases, the steel basis with components united by articulated joints is concerned. These are pillars, supporting joists and ceiling beams that are composited with a concrete desk so that they ensure the position stability in a horizontal direction. The both options differ from each other by the position stability method in a vertical direction. In the first case, the vertical clamps avoid the deformation. In the second case, two frame constructions are designed for both yawing directions. The result was the choice of the first method that is discussed in a more detailed way further.

The Technical Means of Forestalling Further Vehicle Movement: Legality, Proportionality, and Other Application Problems
Bušek, Tomáš ; Adamec, Martin (advisor) ; Staša, Josef (referee)
Thesis Title The Technical Means of Forestalling Further Vehicle Movement: Legality, Proportionality, and Other Application Problems Abstract This thesis analyses the institute of the technical means of forestalling further vehicle movement, the so called "clamp", from a theoretical and applicational viewpoint. Its aim is to present a detailed description of this institute, explain the modes within which it is used and the differences among those modes of application, and present the differences of applying this institute by different authorised authorities (i.e. Police of the Czech Republic, Customs Organisation of the Czech Republic, municipal police). This thesis also aims to analyse the contemporary use of this institute in practice, namely concentrating on the frequency, methodology, and legality of this application. A substantial part of this thesis consists of the research and analysis of the expenses of the use of the afore-mentioned institute. The focus of the analysis of expenses is on their legal grounding, character and the circumstances taken into consideration when determining the full extent of the expenses regarding specific cases. Considering these findings, the final part of this thesis focuses on reflecting the possibilities of improving the current state of the matter. The institute of...

Application of drawingless documentation in the design of a milling clamping device
Schneider, David ; Michalec, Michal (referee) ; Svoboda, Petr (advisor)
The bachelor's Thesis describes the construction of a milling fixture for clamping a component on a machine tool using drawing-less documentation. Available methods of clamping workpieces for machining are described here, and the creation of drawing-less documentation is further explained. Today, in the vast majority of cases, classic drawing documentation is used, which is in many ways more tedious than the processing of described 3D digital data about the model. The work describes the creation of drawing-less documentation on a specific design solution of a milling clamping device. This solution is developed on the basis of three proposals for possible conceptual solutions for the clamping fixture. Complete, drawingless documentation of all individual parts of the product. The bachelor's thesis shows the advantages of drawing-less documentation compared to 2D drawings of components, but also mentions shortcomings that reduce the overall impression. A possible improvement that could simplify the presentation of digital model data is suggested.
