Order Tracking Analysis
Structural resonances of variable speed rotating machines (engine, gear box, motor) lead to critical NVH durability and performance issues. OROS order analysis and tracking techniques allow to identify sources of such noise and vibration.
Synchronous Order Analysis (SOA)
Provides stable and repeatable measurements for any speed-varying machinery. Using proven real-time angular resampling algorithms, SOA extracts amplitude and phase of orders; even from fast transients.
- Up to 40 kHz real-time analysis
- Time domain filters (A, C, Integrators)
- Adjustable keyphasor phase (edge/order 1)
- 1/32nd order resolution
- Order or angular domain averaging
- Max order contribution search
- Simultaneous order analysis on 2 shaft
Waterfall & Profiles
Collect and synchronize all data generated by analyses. Results are sorted based on a choice of references for the Z Axis (RPM, time and levels) and represented in 3D or profile views (Bode plots, cross-phase tracking, …). The section manager features orders, overall, constant frequencies and spectra extraction in one click.
Constant Band Tracking
Measure gearboxes’ modulated and often buried noise and vibration orders.
