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

This project aims to develop an analysis and design framework to enhance the reliability of the next-generation advanced manufacturing systems with security vulnerability and communication scheduling. Reliable control and filtering of distributed systems is an emerging area of automation and control engineering in the tide of the 4th industrial revolution. Expected outcomes of this project include obtaining analysis criteria uncovering the effect from communication scheduling and cyber-attacks, and developing a novel framework based on co-design perspective to realize the distributed system design, while being applied in the cooperative control of various robots or manipulators in unmanned factories.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

Wearable Assistive Robots, designed to be worn on the human body, show tremendous potentials to provide what the wearer lacks in performing physically challenging tasks, such as seen in manufacturing, agricultural and healthcare industries. However, fundamental challenges still prevent the realisation of such benefits in the practical settings outside the laboratory. This project addresses these challenges by establishing (1) a systematic design approach for wearable robots to achieve the intended task while optimising other relevant considerations, such as human factors and the practical bulk of the robot; and (2) a novel control and interaction strategy to accommodate the variations in realistic living and working environments.Read moreRead less

Interactive companion robot with nanowire-based electronic skin. This project aims to design an interactive companion robot with electronic skin which can communicate with people by touch and enhance their psychological development. Interactive companion robots can improve the social life quality of people with communication disorders and help elderly people. Although touch is extremely important in human communication, most companion robots lack haptic sensing, which degenerates the human-robot interaction. The anticipated outcome is a touchable robot with developmental benefits for autistic children and psychological benefits for elderly people.Read moreRead less
