On-line diagnostic monitoring systems for vibration of machines
Cirhanová, Iva ; Prostredník, Daniel (referee) ; Hammer, Miloš (advisor)
The bachelor thesis deals with diagnostic monitoring systems of machine vibration. First of all, a technical diagnosis with a focus on diagnostic methods, means and diagnostic systems is generally described. Special attention is paid to vibrodiagnostics and termodi-agnostics. In the next part of the thesis there are on-line diagnostic monitoring systems, their parameters and their use in technical practice. Emphasis is placed on systems from SKF, ADASH and ifm electronic. The systems are compared and the economic aspect is briefly outlined. In the bachelor thesis is also evaluated.

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.

Temperature Measurement in Technical Diagnostics
Szmek, Tomáš ; Janečka, Jan (referee) ; Vdoleček, František (advisor)
The purpose of this bachelor’s thesis is to familiarize a reader with possibilities of temperature measurement along with constructions and functions of particular measuring instruments and to present their positive and negative aspects. Both basic contact thermometers used in common life and complex systems (thermovision) employed in the most demanding industrial application are described here. The thesis depicts temperature as a diagnostic value according to which the causes of machinery failures are easily detected and subsequent accidents prevented.

Thermodiagnostics – contact and contact-free temperature measurements
Mikula, Martin ; Jankových, Róbert (referee) ; Hammer, Miloš (advisor)
This thesis is concerned with thermodiagnostics in industrial practise, which is very important for the assessment of technical condition of object on the basis of temperature, in today's time. It includes summary of contact and contact-free methods and their principle, advantages and disadvantages for aplication in industrial practise. Because of thesis it was carried out measurement in company Daikin Device Czech republic with the use of contact thermometer and two available thermocameras for solving of topical tasks relating to production.

Modern approaches in the maintenance field
Pšenková, Tereza ; Řezníčková, Hana (referee) ; Hammer, Miloš (advisor)
This master thesis deals with position of the maintenance in the company structure and with modern management approaches. One of the highest levels of maintenance is the proactive maintenance, which is using the technical diagnostics to find out the causes of failures. The most inportant in case of machines are vibrodiagnostics and thermodiagnostics, which are going to be applied on the motors in company Bosch Diesel s.r.o.

Temperature measurement of a machine tool
Novotný, Petr ; Merenus, Ondřej (referee) ; Hermanský, Dominik (advisor)
The aim of this work is to get acquainted with the problems of temperature measurement, various types of non-contact temperature measurement and types of non-contact gauges. It also tries to explain the basic concepts and knowledge from the field of machine tools and their thermal load. Part of the thesis is to test this knowledge using measurements at Intemac Solutions s.r.o. The acquired knowledge is then evaluated using graphs and tables.

Reengineering of the maintenance system of variable speed drives using multi-parameter diagnostics
Nahodil, Petr ; Helebrant, František (referee) ; Pačaiová, Hana (referee) ; Hammer, Miloš (advisor)
The work is focused on multiparametric diagnostics, which is an important part of machine and equipment maintenance today. It deals with the use of fields such as vibrodiagnostics, electrodiagnostics, thermodiagnostics, tribodiagnostics, assembly and optical measurements as well as other diagnostic methods in order to obtain a complete picture of the monitored devices. The work also discusses the modern procedure of using multiparametric diagnostics to identify the causes of problems and define appropriate measures in the framework of maintenance. The dissertation is based specifically on the implementation of multiparametric diagnostics in the operability of drives with variable speeds and justifies the necessary reengineering of the maintenance system for these devices. The given maintenance system will clearly require a change in the inspection activity primarily in terms of quality, but certainly also quantitative verification and validation of the measured data in situ, an adequate change in the documentation processed by the manufacturer, or by the supplier, conducted by the user, etc. The work itself is based on the basic idea that if I can measure and diagnose something, then I can declare that I know something about it.
