Characterising and suppressing vortex induced vibration. Vortex-Induced Vibration has become the design limiting factor in offshore design of elements such as the flexible pipelines that bring oil and gas to the surface. With rising oil and gas prices it is becoming more economic to explore such resources in deeper waters, which exacerbates the problem. Currently, high factors of safety must be used in the design of such pipelines because of our current lack of understanding of when the vibratio ....Characterising and suppressing vortex induced vibration. Vortex-Induced Vibration has become the design limiting factor in offshore design of elements such as the flexible pipelines that bring oil and gas to the surface. With rising oil and gas prices it is becoming more economic to explore such resources in deeper waters, which exacerbates the problem. Currently, high factors of safety must be used in the design of such pipelines because of our current lack of understanding of when the vibrations occur and their frequency and amplitude. This study will provide insight into the character of such vibrations and also look at means of suppressing them.Read moreRead less

Design of Quantized Feedback for Robust Control Systems. Most modern machineries and industrial processes are manipulated using advanced control technologies. With the recent advances in information technology, more and more control systems operate over communications networks. However, the technologies used in these control systems are seriously lagging behind because they make little assumptions about problems in digital communications. These problems include sampling errors, quantization erro ....Design of Quantized Feedback for Robust Control Systems. Most modern machineries and industrial processes are manipulated using advanced control technologies. With the recent advances in information technology, more and more control systems operate over communications networks. However, the technologies used in these control systems are seriously lagging behind because they make little assumptions about problems in digital communications. These problems include sampling errors, quantization errors, transmission errors and transmission delays. The proposed research will develop a new control theory to address this issue. Our work will help Australia maintain a leading role in the area of control and give the Australian industry advantages in applying modern technologies in control and automation.Read moreRead less

Supervised autonomy for AUVs using limited bandwidth communication channels. This project aims to improve the feedback link between robotic platforms and an operator, to increase the effectiveness of underwater survey operations. During surveys, some level of adaptation is required to allow underwater robots to respond to the data they are collecting.

This project aims to improve the feedback link between robotic platforms and an operator, to increase the effectiveness of underwater survey operations. During surveys, some level of adaptation is required to allow underwater robots to respond to the data they are collecting. It is often difficult to reliably program an autonomous system to identify salient data, particularly when the mission involves searching for particular features whose sensor signatures may be difficult to determine a priori. In contrast, humans are generally good at quickly identifying important data or determining when a mission is not achieving its goals. The project aims to develop novel acoustic communication schemes that will allow communication between the human operator and the underwater robot, exploiting developments in machine learning, network and communication theory.Read moreRead less
Active Vibration Control of a Cricket Bat using Piezoelectric-based Smart Materials Technology. Improvement of sporting equipment performance of late has largely ignored the game of cricket. Using the combined disciplines of advanced materials and control technologies, it is anticipated that the traditional cricket bat can be vastly improved while keeping to bat modification guidelines as specified in the rules of the game.

Improvement of sporting equipment performance of late has largely ignored the game of cricket. Using the combined disciplines of advanced materials and control technologies, it is anticipated that the traditional cricket bat can be vastly improved while keeping to bat modification guidelines as specified in the rules of the game. This project involves the dynamic study of the bat using established experimental techniques. Once the various regions of high strain rates are determined, smart materials technologies will be used to reduce the transient vibrations transmitted to the batsman. The effect of this monitoring and control is to increase the comfort level and hence, effectiveness of the batsman.Read moreRead less

Comfort and ergonomics: Innovative seating solutions for commercial vehicles. This project aims to develop a 6-degree-of-freedom seating system for commercial vehicles, including heavy duty trucks and mobile machinery, to reduce unwanted multiple directional vibrations to the driver’s body. Long-term exposure to vibrations from uneven road surfaces, vibrating tools, and vibrating machinery affects driver comfort, fatigue and safety, and can also cause neck and shoulder pain, lower back injuries, and spinal injuries. The expected outcome of the project is a comfortable and ergonomic seating system that, agriculture, transportation, mining and construction vehicles, both in Australia and internationally, can widely use.Read moreRead less
