Condition monitoring of large, horizontal low speed slew bearings. Remote sensing has often been used to collect vibration data .To date, no current analysis technique has produced results that appear consistent due to the low speed (less than 1 Hz), and the acyclic characteristic of the rolling element anti-friction bearing.
The contact vibration energy between rolling elements and races is low due to the low speed of the motion, and thus the vibration produced is masked by the general runnin ....Condition monitoring of large, horizontal low speed slew bearings. Remote sensing has often been used to collect vibration data .To date, no current analysis technique has produced results that appear consistent due to the low speed (less than 1 Hz), and the acyclic characteristic of the rolling element anti-friction bearing.
The contact vibration energy between rolling elements and races is low due to the low speed of the motion, and thus the vibration produced is masked by the general running vibration and is not readily distinguishable from the background vibration of the rotating structure. The aim of this project is to use remote sensors to collect information about the state of horizontal slew bearings and develop an analysis technique that will predict the short to medium term behaviour of horizontal slew bearings. The technique has the potential of saving $3.2 million in loss production per an unplanned breakdown of a slew bearing in a steel plant.

A knowledge of the relationships between input variables and measured output states of a rolling mill should enable significant improvements to dimensional stability of the product being produced and to an increase in availability of the rolling mill. The aim of this project is to develop a methodology for developing relationships between input variables that contribute to the measured output states of fully assembled rolling mill stands and this enable the operator to identify and avoid undesirable mill states.Read moreRead less
Mechanisms of mixed lubrication in rolling. Advanced manufacturing is always a major wealth-creating sector in developed economies. To catch up the revolution in rolling industry, Australia must develop her own technologies, train her own professionals of high competence, and thus increase her share in the international market. The proposed research will enhance Australia's record in production-orientated fundamental research in the field of metal rolling, and stimulate the growth of the world-c ....Mechanisms of mixed lubrication in rolling. Advanced manufacturing is always a major wealth-creating sector in developed economies. To catch up the revolution in rolling industry, Australia must develop her own technologies, train her own professionals of high competence, and thus increase her share in the international market. The proposed research will enhance Australia's record in production-orientated fundamental research in the field of metal rolling, and stimulate the growth of the world-class Australian industry, BlueScope Steel, and train young engineers most needed by the country. The research outcome will bring about long-term benefit to Australia.Read moreRead less

Australia's furniture manufacturing industry is a major contributor to the economic wealth of the Australian economy with an annual $9.5 billion turnover. The Australian Furnishing Industry Association (AFIA) estimates that there are 15,000 furniture design and manufacturing firms, employing 66,000 people. However, Australian manufacturers are experiencing high levels of fixed cost (associated with plant and equipment) and low equipment-utilisation ratio and long delivery time. This research aims to enable Australian manufacturers to stay competitive in the dynamic global market, by providing a better strategy to allocate their constrained resources including workforces and facilities.Read moreRead less
