The acoustics & vibrationsÌýlaboratory provides support for teaching and research within the areas of acoustics, vibrations, wear and machine condition monitoring. This involves the measurement and analysis of air-borne or structure-borne noise and vibration, and wear and fault analysis.Ìý

The laboratory is well-equipped with state-of-the-art noise and vibration instrumentation and wear testing facilities, ranging from sound level meters, multi-channel signalÌýanalysers, shakers, sound sources, accelerometers, microphones and multi-functional tribometers. The instrumentation and measurement systems are complemented by computer-based modal analysis and data processing systems.Ìý

Current research undertaken in the Laboratory coversÌýthe following:Ìý

  • Signature management of maritime platformsÌýÌý
  • OptimisationÌýof mufflers for improved acoustic performanceÌýÌý
  • Diagnostics of helicopter gearboxes and gas turbine enginesÌýÌý
  • Modelling of faults in IC enginesÌýÌý
  • Geared systems and rolling element bearingsÌýÌý
  • Signal processing, machine condition monitoringÌýÌý
  • Diagnostics and prognosticsÌýÌý
  • Wear analysis of mechanical and bio-engineering systemsÌý
  • Research into active vibration control.Ìý

Research work undertaken in the Acoustics and Vibration Laboratory is in collaboration with theÌýDefenceÌýScience TechnologyÌýOrganisationÌý(DSTO).Ìý
