This theme aspires to apply the latest capabilities in dynamics, vibration, acoustics and control for sensors/transducers, data acquisition and signal processing to the unique local and more globally relevant engineering challenges in above and below rail contexts. Colleagues from this TRC theme also lead our unique UTS Tech Lab Vibration Lab, Acoustics Labs and Structural Dynamics Testing Facility as well as our city centre campus located Dynamics and Mechanics of Solids Laboratory.

Our world-leading capabilities

  • Non-contact vibration measurement techniques, especially laser Doppler vibrometry, digital image correlation (DIC), LiDAR/V for geometrical campaigns, fibre-optic based approaches (fibre Bragg and Brillouin scattering) and other associated approaches.
  • The development of analytical, numerical and computational simulation and prediction techniques, especially for structural and acoustics problems and their correlation from experimental datasets.
  • Multi-body simulation and finite element model updating.
  • Non-destructive testing, vibration qualification testing, pseudo-static and dynamic testing, experimental and numerical modal analysis for structural dynamic characterisation.
