Method and apparatus for signal signature analysis for event detection in rotating machinery |
| 摘要 |
<p>A method for analyzing vibration including: acquiring a vibration signal (18); isolating (20) a vibration signal event in the acquired signal; determining (30) a frequency of a damped sinusoid of the vibration signal event, wherein the damped sinusoid characterizes the vibration signal event, and using the characteristic damped sinusoid to identify (36, 40) an occurrence of the vibration signal event in another vibration signal.</p> |
