Experimatal Analysis of Windshield Wipers Motors
Dočekal, Martin ; Mach, Martin (referee) ; Hájek, Vítězslav (advisor)
The work deals with the methods of measurement of small DC motors, especially motors used for drives wiper’s mechanisms. Furthermore, describing the internal structure and function of wiper’s engines. Measurement of these engines is carried out mainly dynamometers which is described in more details in the work. However, measuring systems consist not only from the dynamometer but also many other components such as controllers, software for testing engines, various stands, temperature and speed testers, and many others. These components are taken into account, when selecting the most suitable measuring system. There are also various systems analyzed and compared in terms of both technical and economic parameters, but also in terms of measurement options, such as immediate viewing characteristics on a PC monitor of the system assembly, the possibility of measuring the friction torque, efficiency, heating, etc. In conclusion, there is a recommendation of measuring system which I chose as the best option according to its parameters.

Hydraulically driven screens
Forman, Ladislav ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The main objective of this work is the calculation of selected parts of hydraulically driven screens such as cleaning equipment before entering the small hydro power plants. The thesis is divided into two parts. The first part focuses mainly on the calculation of hydraulic mechanism for cleaning screens. The second part contains a drawing of the general assembly hydraulically driven screens and sub-assemblies.
