Data-driven, automated NVH testing—test and analysis for motorized assembly manufacturing 

One of the leading issues affecting customer satisfaction for motorized assemblies is unwanted noise or vibration. Some manufacturers rely o subjective testing of their products, having workers listen to or feel for anomalies. Others struggle to move this testing from the lab into the manufacturing environment. 

Sciemetric’s approach to sound and vibration analysis brings noise, vibration and harshness (NVH) testing onto the production line and enables the application of a more reliable, data-driven measurement to catch those hard-to-find clicks, whirs or buzzes. Our in-process testing and monitoring solutions automate NVH testing, reducing the reliance on subjective operator-based testing while providing full traceability to prove product quality and enable root cause analysis. 

Typical issues identified using Sciemetric’s intelligent process monitoring system:

  • Noise level, resonance
  • Loose, rubbing, or missing components
  • Valve noise
  • Surface defects
  • Misalignments
  • Cracks
  • Gear noise and defects
  • And more!

Using Sciemetric’s waveform data for more accurate NVH testing 

NVH-sigPOD-screens
Sciemetric’s use of unique digital process signature technology (waveforms) provides advanced measurement and insights for clearer, more accurate NVH testing. Using microphones or ICP-based accelerometers, etc., this in-line NVH testing approach provides more accurate analysis even under noisy conditions. A range of signatures are used to derive a pass/fail decision during sound and vibration testing, including:

  • Vibration (using an accelerometer)
  • Sound (with a microphone)
  • Electric current
  • Time domain, FFT
  • Synchronous math, statistics
  • All signature data is stored by serial number
