EMC antenna
Tenora, Jan ; Pokorný, Michal (referee) ; Láčík, Jaroslav (advisor)
The goal of this master’s thesis was to design antenna working in frequency range from 30 MHz to 1 GHz. Designed biconical antenna requires balanced feed to work properly, therefore designing the balancing unit based on discrete components was necessary. Designed antenna was also constructed and its return loss, gain and radiation patterns were verified by measurement. This master’s thesis also introduces readers into principles of antenna measurements of disturbing signals in the area of EMC and compares different types of antennas for bands of meter and decimeter waves.

Five-cylinder in-line diesel engine with balancing unit
Štefaňák, Petr ; Dundálek, Radim (referee) ; Píštěk, Václav (advisor)
The purpose of this work is design of a five-cylinder in-line diesel engine with the given initial parameters. The work will be analyzed by balancing the engine, remove the effects of unbalanced masses by the unbalance of the crankshaft and separate balancing unit. It will also be analyzed driveline torsion vibration, followed by reducing the effects of torsion vibration by using rubber torsion vibration dampers. At the conclusion will be modal and stress analysis of the crankshaft using the FEM program.

Three cylinder diesel engine for commercial vehicles
Briš, Tomáš ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
The diploma thesis deals with a design of a crankshaft for a three-cylinder diesel engine for commercial vehicles. The engine is a member of a unified line of engines with the number of cylinders from two to six. The main points of the work are a draft of the crankshaft configuration, the balance of inertial forces and the moments in the crank mechanism, creation of drawings of the crankshaft and finally carrying out a strength analysis of the part, taking into account torsional vibration. The aim is formation of a part – crankshaft for potential usage in the automotive industry.
