Assessment of Geometry Parameters of Track with Under Sleeper Pads
Škovranová, Michaela ; Volejník, Miloslav (referee) ; Hruzíková, Miroslava (advisor)
The diploma thesis applies to under sleeper pads. It researches thein using and benefits in foreign railvway authorities. Further it assesses track geometrical parameters in the trial track section with under sleeper pads in track Havlíčkův Brod - Okrouhlice and in the railway station Planá nad Lužnicí. There were evaluated measurements of vertical alingnment rails by precise leveling and deviations of track geometrical parameters measured by track meusuring car in the diploma thesis.There is expressed an conclusion about the impact of under sleeper pads on track geometric data in the thesis.

Classification and evaluation of rail wear
Nohel, Rostislav ; Frýza, Josef (referee) ; Galas, Radovan (advisor)
This bachelor’s thesis is focused on the wear of rails. In this thesis, the reader will be firstly introduced to the fundamentals such as nomenclature of wheel and rail, adhesion, adhesion coefficient, contact area, slip, traction characteristic and wear. Subsequently, the fundamental types of material wear (adhesive, abrasive and fatigue) will be explained, which occur in the wheel-rail contact. In the next part, the individual rail defects are analysed with respect to locations. The output of the bachelor’s thesis is overview and description of the most common rail defects which are usually caused by fatigue wear.

Standardized procedure of the machine tool adjustment for change of the machined part type
Nedoma, Tomáš ; Tuna, Jaroslav (referee) ; Lošák, Petr (advisor)
The bachelor thesis at hand is dealing with standardized procedure of machine adjustment in process of machined rail type change in Bosch Diesel s.r.o. Jihlava. In the thesis, procedures of external adjustment of preparations that clamp workpieces into machining centers and overall procedure of machine adjustment are described. The elaborated standardized procedures are included in instruction manuals, which are used by workers of the company for machine adjustments. These “manuals” shall minimize occurrence of defective steps in the adjustment process and prevent their interchange. Mistakes based in incorrect procedure of the workers lead to prolongation of the time necessary for machine adjustment in process of change of machined type by up to hundreds of minutes per month. Bosch Diesel s.r.o. has adopted these instruction manuals and thanks to them shall save couple of tens of thousands euro per year.
