Signal Analysis
Synchronous Accumulation (Order Analysis)
Order analysis is one of the most convenient and efficient methods for diagnostics and balancing of rotating mechanisms and transmission gears. With an RPM sensor and a vibration sensor, it is possible to study the time characteristics of gear vibration signals. It is a well-known fact that a signal from a vibration sensor is affected by signals from other sources. To tune out from the disturbing signals, the synchronous signal accumulation method is used. For each shaft rotation, the RPM sensor provides a rotation mark. This signal serves as a triggering strobe for the vibration sensor signal sweeping. The obtained signal sweeps are combined. All the sources of the signals related to the shaft frequency (frequency of rotation) are accumulated and increased in the accumulator linearly proportionally to the N number of rotations. All other signals that are not correlated with the shaft frequency are accumulated proportionally to N1/2 and in case of a greater number of averagings, the useful signal exceeds the interference level.
