Product disposal responsibility has shifted from consumers to manufacturers. Re-use of components is the most efficient strategy for product recovery, which requires reliable methods for assessing the quality and remaining life of used components. The aim of this project is to develop a lifetime model to estimate the remaining life and quality of a used component. This will enable manufacturers to estimate the potential reusability of a component without going through costly and time consuming disassembly processes. In addition, the data from the lifetime monitoring process will provide information for improving the design and manufacture of environmentally friendly products.Read moreRead less
A new abrasive waterjet milling technology and process models for fabricating energy-efficient electrical machines from amorphous magnetic metal laminations. As the most energy-efficient core material for electrical machines, amorphous magnetic metal (AMM) can save more than 36% of the energy wasted by ordinary electrical motors. Since electrical motors consume about 70% of all the electricity generated, if all electrical motors in Australia use AMM as the core material, an annual energy saving ....A new abrasive waterjet milling technology and process models for fabricating energy-efficient electrical machines from amorphous magnetic metal laminations. As the most energy-efficient core material for electrical machines, amorphous magnetic metal (AMM) can save more than 36% of the energy wasted by ordinary electrical motors. Since electrical motors consume about 70% of all the electricity generated, if all electrical motors in Australia use AMM as the core material, an annual energy saving worth approximately $4 billion and an annual reduction of 16 million tonnes of greenhouse gas emission in Australia are expected based on the predicted electricity consumption in 2010. This project will develop a new technology for fabricating larger electrical machines from AMM laminations. It targets the national research priorities in Frontier Technologies and An Environmentally Sustainable Australia.Read moreRead less

Summary
A Non Contact Facility For Measuring Irreversible Energy, Residual Stress, and Full Field Stresses for Critical Rail Infra-Structure Assessment. To meet the national rail objectives as enunciated in the 2002 Green Paper there is an urgent requirement for a capability for: i) advanced (rail) prototype assessment, ii) rapid assessment of rail infra-structure, iii) for increasing the capacity of existing (rail) infra-structure.

To meet the national rail objectives as enunciated in the 2002 Green Paper there is an urgent requirement for a capability for: i) advanced (rail) prototype assessment, ii) rapid assessment of rail infra-structure, iii) for increasing the capacity of existing (rail) infra-structure. To address this we propose a facility with both a dissipative energy measurement and a 'lock in' thermograpghy capability. Recent Australian developments in thermo-elasticity enables the researchers to extend this facility to measure residual stress in complex components. The ability to measure dissipated energy, residual stress, ultrasonic waves, and full field stress will create a unique research capability.Read moreRead less

Mechanics of mixed film lubrication in strip rolling. Rolling speeds of tandem cold rolling mills for thin steel strip are often limited by hot scratches and self excited chatter vibration, which forces the mill to slow down. Consequently the output is reduced and significant out-of-specification materials produced. Operating practices are guided by experience and trial-and-error method. In this project, a comprehensive model will be produced to quantify the effects of relevant parameters that c ....Mechanics of mixed film lubrication in strip rolling. Rolling speeds of tandem cold rolling mills for thin steel strip are often limited by hot scratches and self excited chatter vibration, which forces the mill to slow down. Consequently the output is reduced and significant out-of-specification materials produced. Operating practices are guided by experience and trial-and-error method. In this project, a comprehensive model will be produced to quantify the effects of relevant parameters that can provide a much better understanding of the rolling process at speeds higher than previously possible, and help to improve its productivity as well as product quality.Read moreRead less

Strip shape performance at tandem cold mill. The shape of the strip at the cold mill are affected significantly by machine conditions and key process variables, and yet the inter-relationship between these key areas are not known and operators rely on trial-and-error methods to operate the mill. At high speeds, the shape of the strip leaving the mill is not good, causeing problems to rolling mills downstream. The project proposed here will integrate practical knowledge and numerical modeling of ....Strip shape performance at tandem cold mill.
