VIBRATION DIAGNOSTICS VIMS-WI2

ADVANCED LEVEL

First training day:

General overview of vibration diagnosis concepts: time course and FFT spectrum, amplitude modulation, phase of the vibration signal
Faults recognition of rotating machines – imbalance, misalignment, damage of mechanical gears, resonance, cavitation, damage of rolling bearings, low-speed machines (ACMT technique), lubrication problems, belt gears
Vibration analysis and electrical current analysis in faults diagnostics of AC motors
Advanced diagnostic techniques and their application – order tracking, diagnostics of variable-speed machines, multi- and cross-channel analysis, low and high frequency analysis, synchronous averaging (Enveloping, Demodulation, others), introduction to ODS

Second training day:

Advanced multi-channel portable vibration analyser with advanced functional modules: multi-channel analyser, run-up/coast-down, digital signal recorder, bump tests, analysis of motor current signature
Online diagnostic system
Practical exercises with the use of a test stand (rotor kit)

Remarks: Sets “vibration analyser – analytical software” will be made available during the training (students should bring their own computer equipment – a laptop with the Windows 10 operating system or higher with the rights to install external software)

DESCRIPTION:

Students of this course will gain high competences and skills in the field of vibration signal processing, analysis of the time waveform, frequency spectrum and phase, cross-channel analysis, natural frequency measurements of machines and structures, and error correction. Advanced diagnostic techniques will be presented as well. The course is intended for people who have mastered the basics of vibration diagnostics and want to deepen their knowledge in the field of correct data collection, analyser configuration, diagnosing various faults and understanding balancing, alignment, structural stiffness analysis, natural frequency analysis. Issues related to the diagnostics of low-speed machines and the diagnostics of electric motors will also be presented.
