Projects

Researchers in the School of Mechanical Engineering have developed new technologies relevant for defence applications. Several examples are listed below.

Diesel Engine Testing Facility The school has a laboratory for conducting acoustic testing of exhaust systems attached to a large diesel engine loaded by a water-brake dynamometer. The facility has been used to develop technologies for reducing tonal exhaust noise.

Adaptive Tuned Vibration Neutraliser An adaptive tuned vibration neutraliser was developed to enhance the attenuation of tonal vibration in a two-stage vibration isolation mount. The system automatically tuned to changes in the frequency of the source disturbance. Learn more

Adaptive Tuned Vibration Neutralizer

Active Control of Gearbox Vibration An active vibration control system was developed to move the shaft of a gear, which significantly attenuated the vibration generated by the gearbox. Learn more

Estimating the Size of Defects in Bearings Detailed analysis of the vibration signature of a bearing can reveal the actual size of a defect, without having to dismantle the bearing. Learn more

Vibration condition monitoring of bearings

Flow Over a Closed Cavity High speed airflow over a closed cavity can cause unwanted fluctuations.
