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.

Machine tool Life Cycle
Mikulka, Tomáš ; Marek, Jiří (referee) ; Knoflíček, Radek (advisor)
The diploma thesis is focused on the determination of the life cycle state of the production machine. The thesis is divided into several chapters. First, the life cycle of the machine is defined, and the phrase used here is given. Subsequently, the work is devoted to maintenance, repairs and modernization of the production machine. Then there is a demonstration of Schaeffler Skalica's corporate structure and individual methods that determine the state of the machine's life cycle. In the next chapter, the machine is described and then the analysis is made for the current state of the machine. Then the analyses created are evaluated.

Predictive machine tools maintenance system with the use of vibrodiagnostics
Semotam, Petr ; Nahodil, Petr (referee) ; Hammer, Miloš (advisor)
This diploma thesis concerns issues of predictive and condition based maintenance system of machine tools with using a vibrodiagnostics. It studies and researches its impacts through the basic processes of the maintenance system and characterizes the vibration diagnosis as its tool and mean. There is also described a process of putting condition based maintenance into practice in the practical part of the thesis. The development is realized at Siemens Ltd. Brno with all its requirements and aspects such as a maintenance audit which means the decision on the suitability of condition based maintenance within the current maintenance system, technical analysis as a part of introduction of vibration diagnosis and the practical example of acquiring, recording and assessment of measured vibration. Prior to the end the economic evaluation of the planned predictive maintenance system and the design of the general model of development and implementation of the maintenance system into practice are included.

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.

Using the RCM in machine maintenance
Ludvík, Radek ; Řezníčková, Hana (referee) ; Hammer, Miloš (advisor)
The master's thesis deals with maintenance in the theoretical part, this part is describing historical development and individual systems. Then explains concepts of vibro-diagnostics and electro-diagnostics. Further work will focus on complex maintenance systems such as Reliability Centered Maintenance (RCM). The implementation of RCM in the manufacturing company is the subject of a practical part.

Maintenance and diagnostics of machine tools focusing on vibrodiagnostics, electrodiagnostics and tribodiagnostics
Houška, Jan ; Řezníčková, Hana (referee) ; Hammer, Miloš (advisor)
Master‘s thesis deals with maintenance and related technical diagnostics of machine tools. Diagnostics methods on which is the thesis focused are vibrodiagnostics, tribodiagnostics and electrodiagnostics. Work includes design of diagnostic system and measurement of vibration and electrical parameters of the machining center. Based on given results from data evaluation, further steps in predictive maintenance and usage of technical diagnostics for machine tools are recommended. Within tribotechnical diagnostics, the thesis is based on evaluation of long-term monitoring of process liquid status, which was used in several machining machines. A procedure for the measurement of selected parameters is proposed and periodical liquid status checks are established.

Measurement and evaluation of laboratory DC drive vibration
Bilý, Michal ; Zuth, Daniel (referee) ; Němec, Zdeněk (advisor)
This thesis encompasses measuring and rating of vibrations in electric machines. The theoretical part begins with a short description of possible causes of vibrations, which is followed by a discussion about what consequences the vibrational effects have on electrical devices. Then there is a description of available vibration sensors. The bigger part is then devoted to analysis of vibratory signal in both time and frequency domains. The practical part is divided into two chapters. The first one describes laboratory demonstration of control drive with DC motor, which is expanded by measurement of vibrations. The second chapter deals with measurement and analysis of said vibrations in the demonstration.
