Course detail
Measuring Techniques for Technical Diagnostics
FEKT-MMTDAcad. year: 2017/2018
The course deals with methods, sensors and instrumentation for measuring noise, vibration, ultrasound and thermovision diagnostics. Students will learn the technique of vibration measurement, noise and speed measurement as well as the basics of spectral analysis, bearings fault diagnosis, balancing and diagnostics of rotating machines. Other topics will be basics of modal analysis, calibration of sensors, use of thermal cameras and ultrasonic diagnostic equipment in industrial applications.

Course curriculum
1. Technical devices for diagnostics - types of diagnostics, sensors and analyzers for diagnosis, methods of testing.
2. Vibrodiagnostics - measuring of vibrations (vibration analysis, spectral measurements, averaging issues, detecting of natural frequencies).
3. Diagnostics of rotating machines, balancing of rotating machines, bearings fault diagnosis.
4. Modal analysis, vibration testing - modal testing, test by vibrations and shocks.
5. Acoustic measurement - acoustic quantities (sound power, sound pressure, sound intensity), near field, far field, acoustical holography.
6. Calibration of the sensors - accelerometers, microphones, gyroscopes; types of calibration (primary, secondary), interferometry, standards.
7. Thermovision diagnostics - thermography, measurement using thermal cameras.
8. NDT methods - ultrasonic defectoscopy, magnetic methods, X-ray methods, eddy-current testing, acoustic emission - methods of testing.
