Machinery Vibration Analysis
This course provides more in-depth discussions of single channel time waveform, FFT, and phase analysis techniques for the evaluation of industrial machinery. It includes acceptance testing, machine severity assessment, use of demodulation and HFD techniques, basic operating deflection shape (ODS), and single plan balancing. Workshops and demonstrations are scheduled throughout the training course to exemplify curricular theory and applications.
