Condition-Based Maintenance Optimisation for Queensland’s Railways. Rail maintainers currently use time-based (scheduled) approaches to balance the costs and benefits of inspections and maintenance. Changing to condition-based maintenance has the potential to reduce costs and improve track condition.

Rail maintainers currently use time-based (scheduled) approaches to balance the costs and benefits of inspections and maintenance. Changing to condition-based maintenance has the potential to reduce costs and improve track condition. This project aims to enable this approach for rail by developing: 1) new track degradation prediction techniques combining Big Data and engineering knowledge; 2) new on-board sensing capabilities for frequent, low-cost track monitoring; 3) novel inspection and maintenance optimisation methods to efficiently allocate resources. The knowledge generated by this project is expected to decrease maintenance costs, safety risk, and track closures and therefore enhance the affordability and reliability of rail travel.Read moreRead less
Development of novel inerter-based damper for platform vibration control. This project aims to develop a novel inerter-based damper to mitigate the excessive vibrations of offshore floating platforms (OFP), which are widely used in the offshore industry for oil exploration. Harsh environmental loads such as wind and waves can induce excessive vibrations to OFPs and endanger their safety and stability. This project aims to develop a novel inerter-based damper that can produce a considerable appar ....Development of novel inerter-based damper for platform vibration control. This project aims to develop a novel inerter-based damper to mitigate the excessive vibrations of offshore floating platforms (OFP), which are widely used in the offshore industry for oil exploration. Harsh environmental loads such as wind and waves can induce excessive vibrations to OFPs and endanger their safety and stability. This project aims to develop a novel inerter-based damper that can produce a considerable apparent mass that is much larger than its physical mass through an amplifying mechanism by translating the linear motion into high-speed rotational motion, which can significantly reduce the mass and cost of the damper. Benefits of the project include more economical and safer OFP designs, which are expected to improve the competitiveness of Australian pillar oil and gas industries.Read moreRead less
Qualitative and quantitative modelling of hydraulic fracturing of brittle materials. Few technologies have caused more concern in the general population than the so called hydraulic fracturing technique, applied to enhance the hydraulic conductivity of resource-bearing rocks by injecting high pressure fluids. The concern revolves around uncertainty with leakage of used chemicals to overlying aquifers, unwanted seismic events and surface subsidence. This research, combining experimental and compu ....Qualitative and quantitative modelling of hydraulic fracturing of brittle materials. Few technologies have caused more concern in the general population than the so called hydraulic fracturing technique, applied to enhance the hydraulic conductivity of resource-bearing rocks by injecting high pressure fluids. The concern revolves around uncertainty with leakage of used chemicals to overlying aquifers, unwanted seismic events and surface subsidence. This research, combining experimental and computational investigations, aims to establish fundamental understanding of key processes controlling fracture formation in brittle materials (coal seams and porous rocks) under the action of hydraulic fracturing. The research outcomes will help to assess and minimise the risks associated with the hydraulic fracturing technology. Read moreRead less
Inerter-enhanced metastructure for structural vibration control. Meta-based technique has been proposed for vibration control recently due to its special wave filtering effect. However, the current techniques are difficult to attenuate low-frequency waves, thus not suitable for civil structural vibration control. This project proposes incorporating an inerter-based element into the unit cell of a metastructure. Due to the unique mass amplification characteristic of inerter element, manipulating ....Inerter-enhanced metastructure for structural vibration control. Meta-based technique has been proposed for vibration control recently due to its special wave filtering effect. However, the current techniques are difficult to attenuate low-frequency waves, thus not suitable for civil structural vibration control. This project proposes incorporating an inerter-based element into the unit cell of a metastructure. Due to the unique mass amplification characteristic of inerter element, manipulating low-frequency waves becomes possible. Practical designs are developed and applied to control the adverse vibrations of engineering structures induced by three typical vibration sources. Comprehensive analytical, experimental and numerical studies are carried out to examine the effectiveness of the proposed method.Read moreRead less

Water is a critical resource in Australia and as pressures on water resources increase, water recycling has emerged as an important component of water management practises throughout Australia. Decentralised wastewater treatment systems (or package plants) offer opportunities for water recycling in regional communities; however this application is limited by our understanding on the removal of contaminants of concern through these treatment systems. This project will assess the suitability and efficiency of decentralised membrane bioreactors (MBRs) for the removal of endocrine disrupting chemicals (EDCs), pharmaceutically active compounds (PhACs) and pathogens in accordance with the 2006 National Guidelines for Water Recycling.Read moreRead less
