Reliability and Diagnostics

Lecturer:

Pavel Bach (gar.), Petr Chvojka (gar.)

Tutor:

Pavel Bach (gar.), Petr Chvojka (gar.), David Burian, Jiří Drobílek

Supervisor:

Department of Production Machines and Equipment

Synopsis:

Suject SD describes methods, practical case studies and measuring instruments used for machine tool diagnostics. Vibration measurements and acoustic are the main topic discused in the frame of the subject. Special care is taken to standards ISO and ČSN used for practical measuremets.

Requirements:

basics of vibration theory

design of machine tools

Syllabus of lectures:

Introduction into vibration measuremnts

Vibrodiagnostics I - spectra

Vibrodiagnostics II

Signal alanyzing techniques, FFT envelope

Bearing diagnostics

Tribodiagnostics

Sensors and measuring instrumentation

Geometric accuracy of axes of rotation

Balancing techniques I

Balancing techniques II

Machine tool accoustics

Basement of machine tools

Thermodiagnstics, diagnostics of electromotors

Uncertainty of measurements, expert systems

Syllabus of tutorials:

Measuremnt of noise levels

Vibration od machine tool in accordance with ČSN200065

Measuring of vibration spectra, filtration

Diagnostics of machine tool spindles

Geometric accuracy of axes of rotation

SW Signal analyser

Study Objective:

Aim of this subject is to familiarize students with standards ISO and ČSN during practical measurements hold on the real machine tools. A practical handling with measurement instrumentation is the next goal of the subjest.
