Course detail

Diagnostics Systems

FSI-ZDIAcad. year: 2014/2015

The course familiarizes students with modern technical diagnostics and its importance for the design and operation of contemporary machines. It defines the basic concepts and categories of reliability and technical diagnostics. Special emphasis is placed on tribodiagnostics and vibroacoustic diagnostics, especially on the methods of processing a diagnostic signal in the time and the frequency domain. The significance of electromagnetic compatibility for the reliability of a modern mechanical unit is discussed. Also, course deals with the noise as a diagnostic quantity and with the professional software platforms for diagnostic systems.

Learning outcomes of the course unit

Students gain both theoretical knowledge and practical skills with methods of the machine technical condition and reliability assessment. They acquire also practical experience with non destructive testing and technical diagnostic experiments. Students will be able to express correct inputs for experiment control and analysis of the results. As well, they will be able to design and assembly mathematical models for diagnostics. Students gain knowledge of the vehicle diagnostics and tribodiagnostics of machines.

Prerequisites

Knowledge in area of electronics and measurement.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Teaching is supplemented by practical laboratory work.

Assesment methods and criteria linked to learning outcomes

Course-unit credit is awarded on the following conditions: active participation in the seminars, good results of elaborated laboratory exercises.
Examination: course is finished by the final test during 4th week. In the test, the student has to prove knowledge of basic terms, important principles and their application.

Aims

Goal of the course is to introduce methods of the experiment organization and to extend subjects discussed in previous Electronic and measurement course. Measurement of physical quantities specific for technical diagnostic experiments is discussed. The aim is to gain knowledge required for diagnostic model design and assembly. Attention is also paid to the branch of diagnostic of vehicles by CAT/CAME methods (computer aided testing/computer assisted measurement and evaluation).

Specification of controlled education, way of implementation and compensation for absences

Attendance at lectures is recommended; attendance at laboratory practicals is obligatory and checked by the lecturer. One absence can be compensated by attending a seminar with another study group in the same week, or by elaboration of substitute tasks. In case of longer absence, compensation of missed lessons depends on the instructions of course supervisor – special task elaboration.
