Engineering Diagnostics Laboratory

 

Purpose of the laboratory
Aims consist of achieving the diagnosis tests and measurements emerged in the general mechanical engineer applications. Moreover, repairing of machines is general part of the whole that is in close relation to the purposes of BSc mechanical engineer education.
After revealing defects of the certain machine by diagnostic methods further interventions are required which are mainly executed in the course of „machine-repairing„ courses.
Faulty machine parts are belonging to the laboratory for the students to examine their behaviour under certain conditions are close to real industrial applications. Hence all of them could get the knowledge far enough to make non-destructive material test as a broadly used method of machine fault diagnosis.
Student make a report they are asked for writing a detailed description about the steps of the measurements, their aims, to draw the conclusion and to make general analysis of the problem. Due to the high standard requirements, they are participated in deep knowledges are needed and help them to become essential member of the work team of their future work places.

Competence of the laboratory
One of the most used methods to analyse the status of a machine without destruction is the vibration analysis. Vibration parameters as displacement, velocity, acceleration should be measured in order to get information about the condition of the machines. Levels are mostly regulated by ISO 10816 standard. The higher values are measured the worse machine condition appeals. The laboratory is equipped with several vibration gadgets from the simplier to the more sophisticated ones. With the vibration analysis some typical machine faults can be detected like shaft deformation, unevenness, cracks, bearing faults etc. Sensors must be fixed steadily on the machine parts with magnet, glue and bore with thread inside. Not only the intensity of the vibration can be measured but the vibration spectrum as well. Fourier transform is a general method to change time to frequency so that signals could be showed for further analysis. Hand-held units as VibChecker SPM and more accurate ones as SPM Leonova Infinity can make this task easier. Furthemore it is sometimes needed to revise the status of roller element bearings. General vibration method does not applicable to make a reliable decision whether the unit is good or should be changed. SPM methods was developed to analyse bearings. On the inner or outside rings of the bearing several faults like cracks, holes can developed especially under high loads with extreme RPMs. These faults generate shock pulses with energy of low values. They are detected only with very sensitive special sensors that can filter out the peaks from the vibration spectrum efficiently. BearingChecker hand-held device and SPM Leonova Infinity are designed to check bearings.
Besides vibration measurements we broadened the diagnosis methods with acoustic tests. In the laboratory there are SPL units capable of measuring noise from 20 Hz to 20000 Hz. Additionally, noise spectrum can be calculated by Fourier transform as it was shown previously in the vibration measurement. It serves information which frequencies are the higher ones in the whole spectrums. It is important if one would like to apply hear protective kits because their SNR value is related to frequency.
If frequency is above 20000 Hz ultrasonic sensors should be used for detecting leakages, cracks both in machine parts and in pipe line systems. It is a perfect way for checking valves as well.
Endoscope can detect inner parts of a complex unit by leading a fibre glass pipe into the machine. Through optical elements tiny parts can be scaled up then recorded if necessary. 
Lubrication tests can be applied in this laboratory greases, oils are commonly analysed by tribology ways.
Finally, I would like to emphasize the importance of thermography measurements. TIC type Flir help the tests in order to classify machine elements, their faults on the basis of thermal radiation.
