Course detail

Diagnostics Systems

FSI-ZDIAcad. year: 2009/2010

The course "Diagnostic Systems" familiarises students with modern technical diagnostics and its importance for the construction 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 accentuated. Also discussed is noise as a diagnostic quantity, as well as the software of professional diagnostic systems.

Learning outcomes of the course unit

Students will have an overview of contemporary possibilities of experimental detection of some mechanical quantities needed for an assessment of failure-free operation of machines and their parts. They will be provided with fundamental practical knowledge of and experience with these problems. They will be able to formulate real requests for these activities and will have a grasp of evaluation and interpretation of the results.

Prerequisites

The course is a follow-up to the course “Electronics and Measurement” and deepens and widens the knowledge acquired.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

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, - solution of additional tasks in case of longer excusable absence. Examination – combined (written and oral). In the written part the student has to prove knowledge of basic terms, important principles and their application; the oral part takes the form of a discussion over the written part and records from laboratory exercises.

Aims

Students will acquire theoretical and practical knowledge of and experience with contemporary methods, experimental instrumentation and computer technology intended for detection of input data, and for technical diagnostics. Also dealt with are the kinematic quantities, forces, moments, pressures and noise and processing of acquired results with using of CAT/CAME systems.

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

Attendance at practicals is required. One absence can be compensated for by attending a seminar with another study group in the same week, or by elaboration of substitute tasks. Longer absence may be compensated for by special tasks according to instructions of the tutor.
