Analysis of piezoelectric energy harvester for railway applications
Kubiš, Juraj ; Tofel, Pavel (referee) ; Hadaš, Zdeněk (advisor)
This master´s thesis deals with a piezoelectric energy generator, witch is a device that converts mechanical stress into electrical energy. It is small device that is mostly placed on vibrating structures in order to collect energy. By gluing this piezoelectric layer to the bottom of the rail, it would be a suitable power supply for the communication modules, while obtaining a sufficient amount of energy. These modules ale used as self-powered sensors stations with vision to monitor the condition of railway lines in more detail. The problem of these modules is their power supply, when the energy gain from the generators located on the railway line is insufficient. By acquiring a new energy source, this problem can be greatly simplified and lead to simpler inspection and earlier maintenance on railway lines.

Electromagnetic energy harvesting resonator for train trackside
Rusková, Miroslava ; Singule, Vladislav (referee) ; Hadaš, Zdeněk (advisor)
The aim of the diploma thesis was to design an electromagnetic generator to the purpose of supplying signalling and safety devices on the rail tracks. The electromagnetic generator is a separate electrical source, which is mainly needed for safety in the case of not covered tracks by electrical installation. The thesis proposes two types of electromagnetic generator and one with non-linear stiffness, which are designed for the passage of trains with low frequency.
