CONCLUSIONS CAUSE • Low-frequency periociic stimulus (0.5 Hz - 1 Hz) • Perioci (frequency) correlates with operating conciitions • Amplitucie correlates with operating conciitions • Detecteci anci measureci with envelope analysis, in the time ciomain (RMS) EFFECT • Vibration at a nearly constant frequency (2.3 Hz - 2.4 Hz) • Frequency not relateci to operating conciitions • Frequency relateci to the natural vibration frequency of the mechanical element, subjecteci to bounciary conciitions (constraints, ciegrees of freeciom) • Detecteci anci measureci with frequency ciomain analysis © 2025 TEKNEENGINEERING
