Vibration monitoring from rolling bearing
Langr, Pavel ; Klusáček, Stanislav (referee) ; Štohl, Radek (advisor)
This bachelor thesis deals with problematics of vibration measurement and diagnosis of rolling bearings. The first part is focused on describing basic terms, defines what vibration and bearings are and how vibration occur as a result of ball bearing defects. The second part of this bachelor thesis deals with vibration diagnosis according to ČSN ISO 10816 standard and describes basic principles and rules, to comply with this standard. Third part of the thesis deals with instrumentation of IFM electronic company, used for vibration diagnosis. The last part is attended to design and realiyation of laboratory exercise, which is meant to familiarize with ball bearing vibration problematics.
Vanadium cells as a source and storage of energy
Langr, Pavel ; Chladil, Ladislav (referee) ; Novák, Vítězslav (advisor)
This semestral thesis deals with problematics of redox flow batteries, especially vanadium batteries. The first part is focused on describing basic terms, describes redox batteries and explains chemical processes. It also deals with vanadium batteries properties and construction. The second part of the thesis describes diagnostic method of spectroscopy, which seems to be very perspective for examining attributes of vanadium redax batteries.
