Quantitative analysis of dynamic performance of vehicles with uncertain system parameters and road inputs. Ride comfort, road holding and stability of on-road vehicles are not only important quality indicators but major public health and safety issues. To accurately predict and prevent unsafe motions of a vehicle under all circumstances is still a major technological challenge. The research, which aims to develop a novel design theory, presents a significant step forward in tackling the challeng ....Quantitative analysis of dynamic performance of vehicles with uncertain system parameters and road inputs. Ride comfort, road holding and stability of on-road vehicles are not only important quality indicators but major public health and safety issues. To accurately predict and prevent unsafe motions of a vehicle under all circumstances is still a major technological challenge. The research, which aims to develop a novel design theory, presents a significant step forward in tackling the challenge in the quantitative performance analysis of vehicles with various uncertainties. The acquired knowledge will assist engineers in developing safer vehicles and also benefit the aeronautical, military and other transportation industries. The wider community would benefit by potentially reduced death rates and fatal injuries caused by car crashes.Read moreRead less

A Multi-Scale Approach To Reliability And Durability Of Engineering Structures And Sensors. The Longford explosion is an example where a major failure was due to a very small defect. It is estimated to have cost Australia in excess of $1.5 Billion. The acquisition costs of aircraft mean that keeping a fleet operational for a year can produce savings of ~$100,000,000.The automotive industry is designing lighter vehicles. GM Australia has realised that ensuring the durability of these new designs ....A Multi-Scale Approach To Reliability And Durability Of Engineering Structures And Sensors.

GM Australia has realised that ensuring the durability of these new designs is essential. By our participation in the GM PACE program we ensure that the developments are available to the broader Australian Industry. Indeed, to design durable MEM's structures would give Australia a commercial edge.Read moreRead less
Prediction and control of fluid-structure interactions. Fluid-flows create a pressure that can deform the surface of a structure or cause it to vibrate; an extreme example is the fluttering of a flag. Flow-induced vibration of the external panels of vehicles causes damage, noise and can adversely affect performance. This project will develop a wholly new approach for the analysis of these interactions. The versatility and completeness of the approach permits a step-change in the design of panels ....Prediction and control of fluid-structure interactions. Fluid-flows create a pressure that can deform the surface of a structure or cause it to vibrate; an extreme example is the fluttering of a flag. Flow-induced vibration of the external panels of vehicles causes damage, noise and can adversely affect performance. This project will develop a wholly new approach for the analysis of these interactions. The versatility and completeness of the approach permits a step-change in the design of panels, reducing material and manufacturing costs without compromise to safety and performance - an immense benefit for the myriad engineered products or structures that feature flow over a deformable surface.

Taming turbulence: Hydrodynamic stability and flow-structure interaction using grid-free computation. Turbulence is characterized as seemingly disordered fluctuations that impede the progress of an object through a fluid by creating increased frictional or drag forces. Using a new type of fluid-flow simulation, this project will generate advanced understanding of turbulence in the flow over the surface of a vehicle, be it a ship, car, aircraft or within a pipe, with the technological objective o ....Taming turbulence: Hydrodynamic stability and flow-structure interaction using grid-free computation. Turbulence is characterized as seemingly disordered fluctuations that impede the progress of an object through a fluid by creating increased frictional or drag forces. Using a new type of fluid-flow simulation, this project will generate advanced understanding of turbulence in the flow over the surface of a vehicle, be it a ship, car, aircraft or within a pipe, with the technological objective of reducing drag by adhering a compliant skin to the surface. While the correct choice of compliance relies upon understanding very complex flow-structure dynamics, the resulting technology is simple, robust and has low capital and maintenance costs. Clearly, drag reduction reduces fuel costs and lower fuel consumption is environmentally beneficial. Read moreRead less
