This project aims to develop an innovative technology for the production of thin strip with controlled varying longitudinal thickness and shape. The project will propose a new thin strip rolling theory and strip shape control strategy providing an improved understanding of the mechanics of manufacturing thin strips with varying longitudinal thickness. The technology to manufacture rolled products with varying thickness for lightweight structures is in significant demand for the automotive, aerospace and electronics industries to reduce weight through optimum strip thickness and minimum joints. The benefits will include reduced weight, fuel consumption and construction time of automobiles and aircraft when the developed novel thin strip products are used, and therefore reducing manufacturing costs and negative environmental impacts.Read moreRead less

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.

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.
