Application Note: Transmission NVH Testing
The engine manufacturer had issues with inconsistent transmission quality causing unwanted noise and vibration. Sciemetric’s proven NVH test was seamlessly integrated onto their existing EOL test to detect issues such as, valve noise, missing bearings, timing problems, gear and loose rubbing parts in addition to having all data stored in a central location for complete traceability.

Application Note | Power Steering Pump: Vane Defect Detection Using Signature Analysis
A power steering pump manufacturer required a solution that accurately detected the most subtle vane defects prior to final assembly to avoid costly tear downs due to the objectionable noise and vibration (NVH) they can create. A Sciemetric test and analysis system was installed and configured to observe the pressure waveform, allowing easy detection of missing, nicked, bent and slightly stuck vanes.

Application Note: Cam Shaft Grinding Application
A major automotive manufacturer was looking for an accurate quality and process monitoring system to improve yield and reduce costly defects. They were having issues with chatter marks in a cam shaft grinding operation causing engine noise and vibration (NVH) and accelerating engine component wear. Sciemetric’s test and process monitoring system resolved the problem: it measures vibration quality control, condition-based wheel dress frequency, monitors machine health to prevent future defects and more.
