Proactive machine maintenance system
Semotam, Petr ; Řezníčková, Hana (referee) ; Hammer, Miloš (advisor)
This bachelor thesis concerns issues of proactive maintenance, which is focused on machine tools. The most common failures and the most widespread methods of diagnostics of machine tools are described in the thesis. There are also described the procedure of Failure mode, effects and criticality analysis FMEA/FMECA, its possible development in the future with demonstrative presentation of application this analysis on CNC automatic lathe. Subsequently, in the practical part there has been chosen, described and appraised diagnostic of vibrations. Prior to the end the process in field of solving of establishment systems of maintenance has been recommended for SMC Industrial Automation CZ LLC Vyškov.

Immediate diagnostics of aircraft jet engines
Valuch, Tomáš ; Molčan, Anton (referee) ; Šplíchal, Miroslav (advisor)
In this diploma thesis is elaborated design of diagnostic system for small jet engines. The aim is to describe the types of possible failures of jet engines, to determine important parameters characterizing the immediate state of engine and define methods for measurement of selected parameters. The first part is devoted to a description of selected types of small turbojet engines, followed by a summary of the most widely used diagnostic methods for assessing the health condition of the engine during operation. The next chapter contains calculation of the engine thermal cycle with characteristics of construction components. Then there is analysis of small jet engine failures with a description of their causes and possibilities of identification by diagnostic system. Thesis continues with a description of measurement methods and selection of the required sensors. Next chapter is focused on the proposed diagnostic system for condition monitoring of the engine. The last part is devoted to an excursion in laboratory for jet engine testing at the Technical University in Košice.

Risk analysis of load bearing RC structure review
Bohatec, Jiří ; Laníková, Ivana (referee) ; Šimůnek, Petr (advisor)
Master´s thesis deals with the evaluation of existing structures according to ISO 13822, discusses the dangers that can in determining the reliability of existing structures occur. This standard shall consider the risks by analyzing the possible occurrence and impact of defects (Failure Mode and Effects Analysis). In a concrete example shows a process for determining the reliability and suggest the increase. On a practical example I use a universal risk analysis matrix (Universal Matrix of Risk Analysis) with, identify and quantify the significance of the various dangers associated with project implementation.

Analýza možného výskytu a vlivu vad ve výrobním procesu
Vaňátko, Tomáš
This thesis deals with the problematics of the use of the FMEA method in the manufacturing process of engineering company, which is a certified supplier for the automotive industry. The first part of the thesis is focused on the description of the method , its division and its application. The following part of the thesis contains a description of some basic quality tools, which are used a tool for ist preparation. In the practical part of the thesis there is a decription of the application of the FMEA method process on the specific product by Metaldyne spol. s r.o. The collected data are used for the preparation of the FMEA form, in which precautions to reduce nonquality in the manufacturing proces are determined. The final part of the thesis deals with the technical and economic evaluation of profuction of the lower body of a hydraulic pressure filter PAL2R.
