Advanced Vibration Diagnostics
Course Overview
This course develops the analytical skills required to diagnose complex vibration problems in rotating machinery. It focuses on interpreting vibration patterns, separating faults with similar symptoms, and correlating vibration behaviour with machine design, operating conditions, structural response, and maintenance history.
Participants work through industrial diagnostic cases involving turbines, compressors, pumps, fans, motors, and gearboxes. The course emphasizes a systematic root-cause approach rather than diagnosis based on individual spectral peaks.
Key Learning Objectives
Participants will learn how to:
- Develop an effective machinery diagnostic strategy
- Interpret complex spectra and time waveforms
- Use phase and transient data for fault separation
- Identify resonance and structural vibration problems
- Distinguish mechanical, structural, and process-related vibration
