Noise and Vibration

In the field of noise and vibration, we offer the following:

  • Vibration measurement, analysis and control: Whole-body, hand-arm, structural vibration, modal analysis, operational mode, fault diagnosis, predictive and condition-based maintenance.
  • Noise measurement, analysis and control

We also offer courses on the above mentioned topics.

Structural and machine accelerations are measured and the following done:

  • Condition monitoring
  • Fault finding
  • Modal analysis
  • Active vibration control to prevent and eliminate fatigue problems
  • Noise, vibration and harshness (NVH) measurements and control on automotive vehicles, plants, structures, etc.
  • Hand-arm vibration
  • Whole body vibration

Examples on Noise

  1. Attenuation specification for the Gautrain underground station and emergency shaft ventilation system.
  2. Structure borne noise control in a RG32M and several other military vehicles
  3. Automotive noise control and finding the root cause for acoustic booms
  4. Chute noise reduction
  5. Noise control in a winder house operator cabin

Examples on Vibration

  1. Severity of plant structure vibrations
  2. Motion sickness on railway vehicles
  3. Fault finding on machinery
  4. Structure vibrations and condition monitoring using the modal assurance criterion
  5. Plant structure vibration severity
  6. Vibration control using dynamic vibration absorbers
  7. Vibration isolation of sensitive electron microscope at the University of Witwatersrand
  8. Injector plunger vibration
  9. Crack detection from supersonic vibrations on injector clamps
  10. Whole body and hand-arm vibration severity assessment in South African mines
