Analysis of SMART Material Usage in case of Active Vibration Sensing
Rabčan, Jakub ; Věchet, Stanislav (referee) ; Hadaš, Zdeněk (advisor)
This diploma thesis deals with the possibility of vibration sensing and vibrodiagnostics based on the use of so-called "SMART" materials such as piezoelectric layers or structures. Research studies have examined the general overview of vibrodiagnostic methods and their analysis of the possibility of sensing vibration by piezoelectric structures. This was followed by measuring and evaluating the results using various vibro-diagnostic methods. The results were compared with those obtained by sensing vibration using an accelerometer. We also dealt with the problem of detecting the deformation of the device by sensing vibration with piezoelectric structures. The last part was programming the "Myrio" to capture and evaluate the vibration using Labview.

Analýza SMART zdrojů elektrické energie pro železniční dopravu
Zapletal, Vít ; Smilek, Jan (referee) ; Hadaš, Zdeněk (advisor)
This master thesis deal with analysis of possible alternative energy sources for health monitoring of railway trafic. Mainly focus on energy harvesting via SMART materials, specifically materials with piezoelectric and magnetostrictive properties. First theoretical background and real concepts are introduced, followed by material modelling and simulations. End of thesis cover parameter suggestion and SMART materials comparation and valorizations.
