Performance optimisation of turbocharged engine for Formula Student
Špičák, Milan ; Janoušek, Michal (referee) ; Svída, David (advisor)
Diplomová práce je zaměřena na výběr pohonné jednotky pro Formuli Student, sestavení spolehlivého výpočtového modelu za využití pokročilého testování. Dále se zaměřuje na přípravu vhodných podmínek pro testování, samotné testování a následnou kalibraci řídicí jednotky pro validaci simulací a také pro efektivní a spolehlivé řízení motoru v náročných závodních podmínkách. Je zároveň součástí komplexního projektu, který se zabývá celkovým vývojem přeplňovaného jednoválcového motoru pro tým TU Brno Racing.

Control circuits of eddy-current brake
Hofmann, Oldřich ; Knobloch, Jan (referee) ; Huták, Petr (advisor)
The thesis deals with the design of control circuits for the eddy-current brake, which will be used as main component of the dynamometer. The thesis focuses on the design of transistor inverter used for driving the eddy current brake and the design of speed regulation. The thesis also describes various types of brakes used in dynamometers and the overall concept of dynamometer electrical systems. An integral part of the thesis is also the test of the current controller and simulation of the control system at MATLAB – SIMULINK.

Innovation of load test stand for electric drives
Martinek, Jan ; Marada, Tomáš (referee) ; Huzlík, Rostislav (advisor)
The theses presented proposes an innovation of load test stand for electric drives. It begins with a general overview of load test stand types, their manufacturers and measurement methods in load and no-load situations. Next part analyses current circuit diagram of the load test stand and its risks. This is followed by a proposal for innovation of the circuit diagram which is divided into electrical and control part using current load test stand and its mechanical parts. A wiring diagram is created, the control part is processed by the Logosoft program. The design is evaluated from the safety point of view and modified to meet applicable technical standards.

Measurement of internal combustion engine performance on a chassis dynamometer
Farka, Jan ; Ramík, Pavel (referee) ; Štětina, Josef (advisor)
Since the beginning of the automotive industry, a lot of years have passed and the characteristics of vehicles and all its components, especially the engine, are being given greater and greater emphasis both in terms of safety, performance and ecology. The performance of the internal combustion engine, along with a number of other vehicle features, is measured on chassis dynamometers. The aim of the thesis is to describe and analyse the dynamometers produced, the tests performed on them and also to measure the performance of the internal combustion engine on the chassis dynamometer. In conclusion, the assessment of the impact of tests on the automotive industry is just mentioned.

Adjustable portal for hydraulic pulsator Inova
Buchta, Tomáš ; Robenek, Dětřich (referee) ; Mazůrek, Ivan (advisor)
The aim of this thesis is the innovation of the testing device which is located in Institute of Machine and Industrial Design laboratory. The innovation relates to the portal construction design, where will be placed the hydraulic pulsator from the company INOVA Praha Ltd. New portal construction will be designed with respect to specified parameters and requirements and also with regard to the performed tests (damper tests, vibroizolated properties magnetorheological valves tests etc.). The thesis contains detailed analysis of the current tester and detailed analysis of similar machines with focusing on the portal structure and ways of positioning the crossmember. Further parts of the thesis is a detailed description of the design solution, including the computational simulations, attached drawing documentation and experimentally verified functional sample (crossmember).

Analysis of the production process of HPL panels applied for playgrounds made by Kompan Inc
Vik, Michal ; Kouřil, Karel (referee) ; Sedlák, Josef (advisor)
The theoretical part consists of the introduction of company KOMPAN A.S. In addition, there are also introduced the main parts of production, especially CNC workshop, shop floor workplace and warehouse. In the experimental part there is introduced HPL material first. The following is a description of the testing including used tools and materials provided by Kompan Czech Republic s.r.o. Testing was focused on measurement of force load of instruments using piezoelectric dynamometer. The obtained data was processed and analyzed. The last part of the master's thesis is economic evaluation of the production of selected product, which consist of HPL panels. In the following discussion there are evaluate obtained results. In the conclusion part are summarized main results.

Design of a functional model of a chassis dynamometer
Sobota, Matej ; Drápal, Lubomír (referee) ; Štětina, Josef (advisor)
The aim of my diploma thesis was engineering design of 4x4 chassis dynamometer model at 1:10 scale for presentation purpose and for testing RC cars models. The first part describes the current types of chassis dynamometers. The main goal of the thesis was designed the model itself in order to produce some parts of the dynamometer using 3D printing. The work also includes production drawings of individual parts and economic estimate of the entire production.
