Použití metody RCM v údržbě strojů / Using the RCM in machine maintenanceLudvík, Radek January 2018 (has links)
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.

Electrodiagnóstico: protocolo clínico y estandarización de Electrorretinografía (ERG)y Potenciales Evocados Visuales (PEV)en el perro beagleTorres Soriano, Desireé 02 December 2010 (has links)
La presente tesis se ha basado en conseguir dos objetivos fundamentales: diseñar un protocolo clínico de electrodiagnóstico para obtener el electrorretinograma (ERG) y los potenciales evocados visuales (PEV) en el perro beagle, y elaborar un estándar de los resultados para esta raza.Hemos establecido un protocolo clínico de electrodiagnóstico adaptado a nuestro equipo de diagnóstico, a las características de nuestros pacientes y, en general, a los recursos materiales que teníamos a nuestra disposición. De este modo, hemos conseguido realizar un protocolo de corta duración que nos permite evaluar la funcionalidad de las vías visuales del perro y detectar posibles anomalías.Concluimos que el protocolo que hemos establecido nos permite registrar adecuadamente el ERG y los PEV para el perro beagle, así como obtener resultados fiables y reproducibles que podemos considerar como estándar para esta raza canina y este equipo de electrodiagnóstico. / The aims of this thesis were firstly to design a clinical protocol for Electro, electroretinography (ERG) and visual evoked potential (VEP) in the Beagle dog and, secondly, to develop a performance standard for this breed. A clinical electrodiagnostic protocol adapted to our diagnostic equipment was established. This protocol considered the characteristics of the patients as well as the material resources at our Institution. This protocol allowed us to evaluate the functionality of the visual pathways in order to detect any anomalies. It can be concluded that the protocol established in this Thesis allows to record accurately the ERG and the VEP of Beagle dogs. Moreover, the results are reliable and reproducible and it could be considered as a good standard for this breed when these electrodiagnosis tools are employed.

Údržba a diagnostika obráběcích strojů se zaměřením na vibrodiagnostiku, elektrodiagnostiku a tribodiagnostiku / Maintenance and diagnostics of machine tools focusing on vibrodiagnostics, electrodiagnostics and tribodiagnosticsHouška, Jan January 2018 (has links)
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.

Multiparametrická diagnostika generátoru / Multiparametric generator diagnosticsBuchtová, Blanka January 2019 (has links)
The thesis is focused on multiparametric diagnostic of generators at the Dukovany nuclear power plant. One generator was chosen for the thesis and it was examined especially from the practical point of view. The thesis describes current state of the issue with focus on noise diagnostics, vibrodiagnostics and electrodiagnostics. The emphasis is on the system approach of the solution. In the practical part an experiment is designed, described and evaluated. Attention is paid to the conclusions of the performed vibrodiagnostics and noise diagnostics. Data sets are evaluated separately and the relationship between the two diagnostic methods is analyzed. Furthermore, the data set from electrodiagnostics is evaluated and dependencies of electrical diagnostic quantities on other quantities are described. Trends in electrical diagnostic quantities are also monitored. Conclusions and recommendations are formulated at the end of the thesis. It is stated that using multiparametric diagnostics to assess the status of generators in power plants is still in its beginning and that the conclusions of the submitted thesis will contribute to the developmnet in this area.
