Risks in technical diagnostics
Machů, Roman ; Hammer, Miloš (referee) ; Hájková, Alena (advisor)
This bachelor thesis deals with the issue of risks in technical diagnostics. The theoretical part of the thesis is divided into two parts. In the first part attention is paid to technical diagnostics in general and its methods. The second part then summarises the risk issues in general, including examples of different risk assessment techniques. Tables containing examples of the risks associated with selected methods of technical diagnostics, i.e. vibrodiagnostics, tribodiagnostics, electrodiagnostics and thermodiagnostics, have subsequently been produced. These risks have been assessed and mitigation measures have been proposed for significant risks.

Modern approaches in the analysis and evaluation of vibrations in machines and equipment
Mikuš, Juraj ; Poliščuk, Radek (referee) ; Hammer, Miloš (advisor)
The thesis focuses on modern approaches in technical diagnostics. As a part of the implementation, an online monitoring system SIPLUS CMS1200 was programmed. The measured data were transferred using the FTP protocol to a local server. The analysis of the measured data was conducted using CMS X-Tools software. The result of the work is a functional monitoring system that continuously monitors the machine's condition while keeping the operator informed about the current state of the monitored variables. This system helps to prevent unplanned downtime and also financial losses.

Noise control of needle bearings
Štetinová, Iveta ; Krejčí, Jakub (referee) ; Šedivá, Soňa (advisor)
The bachelor thesis deals with the noise of needle bearings. By analysing the noise of the bearings, it is possible to find out the technical condition of the bearing and reveal the types of bearing damage. The beginning of the work is devoted to the theory of bearing noise. Vibration diagnosis methods are described. In the practical part, a manual noise meter is tested, and the investigated values are evaluated by a system for measuring the noise of bearings. The primary objective of this thesis is to find out how the noise of the bearings could be controlled more effectively.

Order Analysis
Honc, Lukáš
This article deals with order analysis. The main purpose is design and realization of own library for online order analysis as a toolkit for LabVIEW. Library contains methods for order analysis including basic functions for processing vibration and tacho signal and functions for tach-less analysis of vibration signal.

Online diagnostics of machine tool MCV 754
Rázgová, Benedikta ; Huzlík, Rostislav (referee) ; Zuth, Daniel (advisor)
This master’s thesis deals with online diagnostics of the machine tool and marginal analysis of surface texture. The first part of the thesis deals with problems theoretically, there are described the machine tools, maintenance, methods of technical diagnostics, specifically online vibrodiagnostic systems and an overview of profile and area parameters. In the practical part, two test samples created under ideal and degraded conditions. In the practical part, two signal processing processes under ideal and degraded conditions are compared using signal analysis from an online vibrodiagnostic system and surface texture analysis. Part of the work is the evaluation of the performed analyzes and recommendations for practice.

Use of Vibrodiagnostics in Forensic Engineering
Záleská, Veronika ; Bradáč, Albert (referee) ; Panáček, Vladimír (advisor)
This thesis deals with the measurement and evaluation of vibration on selected parts of car. Part of the work is devoted to the theory of vibration and noise, which includes, among others, presentations of common disorders of machine parts in terms of vibration. In the practical part of the work were performed out measurements described here and the results analyzed. Last part is in short devoted to the possibilities of using a similar measurement in forensic engineering.

Principles of maintenance of the TPM method
Zahradníček, Lukáš ; Hammer, Miloš (referee) ; Řezníčková, Hana (advisor)
This master thesis concerns modern method of TPM used in the production companies for maintenance of machinery. In the theoretical part, general maintenance is first described, as well as the TPM method. There is also described the technical diagnostics, which was emphasized in the practical part in terms of the use of vibrodiagnostics in predictive maintenance. In the practical part there is presented the proposal for introduction of the TPM method at the SMC Industrial Automation s.r.o. in Vyškov.
