Processing of Operating Load Data for Electrodynamic Test Bench
Prouza, Jiří ; Němec, Martin (referee) ; Novotný, Pavel (advisor)
This master's thesis deals with data processing for an electrodynamic test bench. The thesis presents a theoretical overview of signal distribution, determination of fatigue damage from random vibrations and a description of test benches. The next part deals with setting up the test time reduction in GlyphWorks software. The aim of this thesis is to process and create a procedure for an accelerated fatigue test from data measured during an operational test on a polygon. The data are then verified on an electrodynamic test rig using a Skoda Auto dynamic test room. The final part of the thesis contains data evaluation and a guide explaining how to easily create a test in the relevant software.

FEM analysis of carriage for top drive system of drilling rig and its modification
Plachý, Jiří ; Čížek, Petr (referee) ; Klapka, Milan (advisor)
This diploma thesis deals with FEM analysis and optimization of carriage for top drive system of drilling rig Bentec 350 AC and it is defined as a development contract for company MND Drilling & Services a.s. Intensive drilling leads to damages and repeated occurrence of fatigue cracks on carriage especially along edges of welded ribs in their heat-affected zone. The aim of this thesis is to draft construction improvements of carriage which leads to elimination of damages. Realization of this modifications depends on correct definition of boundary conditions, analysis of damage occurrence as well as verification of carriage drafts with finite element method.
