Order Tracking Analysis
Overview
Order analysis and tracking techniques are essential in measurements with varying rotating speeds. Getting correct results from run-up/down requires specific signal processing techniques.
SOA Main Features
- Up to 40 kHz bandwidth real-time analysis
- Time domain filters (A, C, Integrators)
- Adjustable keyphasor phase (edge/order 1)
- Order or angular domain averaging
- 1/32nd order resolution
Synchronous Order Analysis (SOA) The Synchronous Order Analysis (SOA) plug-in harnesses the DSP powered OROS 3-Series analyzers to provide true order analysis. Signals are resampled with a dedicated tachometer input to be converted to the order domain. Then the plug-in extracts complex orders (phase and amplitude) from fast run-ups and or coast-downs. |  |
 | Waterfall, the Synchronized Data BufferThis specific plug-in collects and synchronizes all data coming from the analyzers data stack. Results are arranged based on a choice of references for the Z Axis (RPM, Time and levels) and represented in 3D or profile views. Identifying the critical analysis item, such as speed, is then much easier as its effects are seen in different dimensions: order, frequency, octave. The section manager of the waterfall plug-in feature orders, overall, constant frequencies and spectra extraction in one click. |
Constant Band TrackingGearboxes generate modulated and difficult to discern vibration orders, which are not easy to extract. The Constant Band order Tracking (CBT) helps engineers acquire those orders with the appropriate band pass extraction. | |
