Overview
- Introduction to Condition Monitoring (CM) including Lubricant, thermography and vibration.
- Introduction to vibration theory to understand machine vibration.
- Instruments details and their selection guidance to meet the requirements.
- Vibration measurement procedure including the concept of anti-aliasing and selection of sampling frequency.
- Signal processing – time domain and frequency domain (spectrum, FRF, etc.), filtering, windowing, envelope analysis, phase analysis, order tracking, orbit plot, etc.
- Theory and experiments on modal testing.
- ODS analysis and rotor balancing.
- Demonstration of a number of industrial case studies linking measurements, data analysis and theory in fault detection & diagnosis, and then solving industrial vibration problems.
- Use of in-situ vibration tests during machine installation and commissioning, and in solving the vibration problem in the aged machines.
Aims
Give a detailed treatment of the in-situ dynamics characterisation, and detection, possibly location and diagnosis of faults in rotating machinery, using vibration analysis.
