"If it goes around, you can make it come around with Rotate!"

ROTATE is ATA Engineering's software package for analyzing noise and vibration from time waveform and tachometer (or other machine speed) signals. The latest release offers many new analysis features including the Vold-Kalman filter, additional data input types and an updated interface. ROTATE PLUS is for advanced analyses, diagnostics and maintenance of machinery, including transmissions, bearings and planetary gears. It post-processes vibration and other types of data from many different data recorders.

Great waterfalls! Super spectrograms! The best cursors in the industry – plus Order Tracking and Torsional Vibration Analysis! All in a program that is easy enough for a rookie technician to use and capable enough for a rocket scientist to really use. If you are familiar with the Windows environment, you’ll feel right at home with Rotate– its ergonomics are Windows-based.

Who Needs Rotate?

Anyone who diagnoses and troubleshoots machinery with rotating or reciprocating parts, or who analyzes acoustic data. This includes engineers, machinery vibration technicians, and consultants engaged in product development, predictive maintenance, and troubleshooting. Some of the industries include automotive, aviation, pulp and paper, rolling mills, power generation, manufacturing and marine.

Try Rotate for resonance searches, signature analysis, performance analysis, dynamic fatigue analysis, balancing and general troubleshooting with exceedingly good results. And now, with batch capabilities and torsional vibration analysis! Kiss shaft-mounted transducers good-bye with Rotate Torsional Vibration Analysis. No more telemetry or slip rings needed!! Rotate can provide you with a complete kinematical description of angular (torsional) vibrations by observing encoder signals—or counting teeth on flywheels.

ROTATE and ROTATE Plus

Rotate Plus is all the software you need to perform advanced analysis and maintenance functions on rotating and reciprocating machinery. With its ability to resample to the angle domain, it can make sense out of the most "dysfunctional" families of harmonics. These large families of harmonics are found in transmissions, bearings and gears where re-sampling to the angle domain pulls out information that fell between the cracks in the noise floor. We've incorporated some special cursors to help you recognize your vibration sources: sideband, gearbox families and rolling element bearing families, plus new analysis functions and capabilities. Rotate Plus includes all the features of Rotate in addition to:

• Order tracking with amplitude and phase
• Elementary torsional vibration analysis
• Great graphics- waterfalls, spectrograms, bode plots, cursors
• Acoustic, whole body and hand-arm weightings
• Sound replay of any time history
• We've incorporated some special cursors to help you recognize your vibration sources, plus new analysis functions and capabilities in Rotate PLUS.  
• Bearing, sideband, gearbox and planetary gearbox cursors
• Order normalization and order zoom
• Advanced Torsional Analysis with high speed counters for windup, torque, transmission error and belt drive dynamics, and calibration for uneven spacing 
• Envelope and Cepstrum analysis and phase demodulation
• RPM traces from waterfalls
• AC coupling and down-sampling

Rotate Plus demos and previews on selected topics:

• Launch series of product demos
• Millstrum, Topic 1 - with spectrogram and definition
• Millstrum, Topic 2 - with waterfall
• Order Normalized Spectra
• Sideband Cursors
• Bearing Cursors

Problems requiring Rotate Plus include the following:

• Identifying individual vibration frequencies in Hz, RPM, or Orders.
• Identifying resonance.
• Dynamic fatigue analysis on the sprung side.
• Torsional vibration analysis without the use of slip rings, shaft-mounted transducers, or telemetry.
• Identifying problems in variable-speed machinery, particularly when the speed changes rapidly or over a large range.
• Troubleshooting intermittent problems that may require hours of data recording.
• Identifying early-stage bearing and gearbox defects.
• Creating a machine speed (RPM) history from vibration data alone (without a tachometer signal).
• Separating order-related vibration from non-order related vibration.
• Identifying problems in crowded, noisy signals from gearboxes and transmissions with closely-spaced and crossing orders.
• Diagnosing machinery when there is a noisy tachometer signal, or no tachometer signal at all.
• Performing advanced machinery diagnosis away from the machinery by "slicing and dicing" time waveform data with powerful analysis tools.
• Creating impressive plots and tables of data to use in reports and presentations.
