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
- Attenuation specification for the Gautrain underground station and emergency shaft ventilation system.
- Structure borne noise control in a RG32M and several other military vehicles
- Automotive noise control and finding the root cause for acoustic booms
- Chute noise reduction
- Noise control in a winder house operator cabin
Examples on Vibration
- Severity of plant structure vibrations
- Motion sickness on railway vehicles
- Fault finding on machinery
- Structure vibrations and condition monitoring using the modal assurance criterion
- Plant structure vibration severity
- Vibration control using dynamic vibration absorbers
- Vibration isolation of sensitive electron microscope at the University of Witwatersrand
- Injector plunger vibration
- Crack detection from supersonic vibrations on injector clamps
- Whole body and hand-arm vibration severity assessment in South African mines
