ORDER ANALYSIS: AN IMPLEMENTATION AND ITS USE IN VIBRATION TIME WAVEFORM SIGNAL PROCESSING

摘要

Mechanical characteristics of rotating or reciprocating machinery change with speed. To properly capture sensor signals to analyze these characteristics, order analysis is often used. There are several techniques for order analysis and one technique, resampling, offers additional advantages for bearing and gearbox degradation analysis. This paper reviews the need for order analysis, two techniques including resampling, and advanced analysis using resampling based order analysis. Advanced techniques include time synchronous averaging, and averaged order spectrum.
