Order analysis at variable speed (tachometer pulse signal)
Measurement sequence with signal import.
Order analysis for run-up and coast-down based on an imported tachometer pulse signal: the speed (tacho RPM) is determined from the pulses through a calculation expression, the vibration signal is analysed through STFT and computed order tracking with speed-synchronous resampling. The results are an order-RPM map and an order spectrum, from each of which the maximum of the 6th order is extracted as a characteristic.
Workflows in detail
-
Order Analysis Measurement
Measurement sequence with signal import.
Start → import tacho → import vibration → order tracking analysis → end; error flow present.
-
Order Tracking
Characteristic block with tacho RPM calculation.
Characteristic start → calculate tacho RPM → STFT → order-RPM map → order spectrum → max 6th order (map) → max 6th order (spectrum) → characteristic end.
