Course detail
Multiparametric Diagnostics of Technical Systems
FSI-9MDTAcad. year: 2021/2022
The course is focused on multiparametric diagnostics of technical systems. Attention is paid first to introduction to technical diagnostics. Furthermore, sensor technology is briefly mentioned as an important part of technical diagnostics. The student is also acquainted with the processing of diagnostic signal. Subsequently, vibrodiagnostics is analyzed in detail with emphasis on the basics of diagnostics of various defects such as static, dynamic and moment imbalance, angular and axial misalignment, bent shaft, eccentric rotor, mechanical release. These are defects that can cause the entire technical system to be taken out of operation and thus cause significant, especially economic, losses. Diagnostics of bearings, pumps, compressors, etc. is also being solved. At present, electro-diagnostics is used within the multi-parameter diagnostics, which is a very promising diagnostic method for describing the state of technical systems. The same can be said about thermodiagnostics, tribodiagnostics, etc. All of this is part of a modern approach, namely the use of multiparametric diagnostics. Therefore, the student will also become acquainted in detail in practical and theoretical terms with the creation of a protocol from the diagnostic investigation of a particular selected technical system. A modern approach to multiparametric diagnostics is not possible without on-line diagnostics, which has become increasingly important especially in terms of methodology, hardware and software. There are many problems associated with this, such as analysis, automation and visualization of big data. Attention is also paid to the use of new modern trends such as digital twin. In the field of multiparametric diagnostics, the use of various methods of artificial intelligence and machine learning is promising.
