Vibration

The first of its kind in Australia, the Vibration Lab incorporates a range of industry-standard non-contact surface vibration measurement systems that allow industry partners to engineer the performance and durability of their products while eliminating unnecessary complexity.

Equipment

  • Laser Doppler Vibrometers (LDVs)
    • Non-contact measurement of surface vibration velocity and displacement. Scanning LDV systems yield a complete vibration survey overlayed on the test sample image.
    • Very high spatial resolution, very low noise floor and very high dynamic range
    • Testing of micro- to macro-scale samples with 1D and 3D as well as differential and angular/torsional (dual beam) vibration
  • Industry-standard dynamic data acquisition systems
    • High dynamic range, built-in signal conditioning, coupled with powerful and comprehensive analysis software suites.
  • First-in-country automatic modal impact hammer integrated with scanning LDV for rapid vibration survey
  • High-speed video and time-resolved Digital Image Correlation for dynamic surface strain measurement
  • Electrodynamic shaker and power amplifier systems for sample/test structure excitation
  • Complementary ‘traditional’ transducers, modally tuned impact hammers, signal conditioning
  • Anti-vibration floors, tables and benchtop systems for high-precision measurement

Capabilities

  • Measure samples that are hot, light or rotating in contexts that necessitate high dynamic and/or frequency range, high spatial resolution and/or remote sensor operation.
  • Samples can range in size:
    • Microscopic
      • Micro-electromechanical systems (MEMS)
      • Naturally occurring/bio-inspired systems
      • Photonics samples
    • Macroscopic
      • Vehicles
      • Aircraft
      • Bridges
      • Other large infrastructure
    • Overlay of vibrational behaviour on images of a sample to detect damage in a structure based on its dynamic characteristics. This information leads to enhanced engineered systems and structures that minimise disruption or premature failure.
    • Finite Element Analysis can be combined with scanning LDV data to enable correlation of computational models, significantly reducing time and cost of manufacture.
