UNSW engineers have developed a device which allows 'pin-on-disk' tribometers to accurately measure heat to within a few degrees. These machines measure the level of friction and wear as two surfaces rub together. Previously the heat generated by interacting surfaces was estimated by the operator but with the addition of this device, this can now be done, in-situ, to a high level of accuracy and efficiency. The device developed can be incorporated into the design of many commercially produced tribometers, allowing for a relatively low-cost in adopting the technology.
- Accurately determine heat to within a few degrees Celsius for most materials
- Adaptable without major redesign to many existing pin-on-disk tribometers
- Can also be used as a completely individual, stand-alone module allowing use with a multitude of tribometers
- Remarkable reduction in both time and inaccuracies of estimating heat generated.
- Can be used in-situ allowing for measurements to be taken at the same time as friction and wear testing.
- Completely non-invasive, will not alter friction and wear characterisation
- Pin on disk tribometers
- Adaptable to other tribometers (sphere, flat etc)
The technology is adaptable to other systems involving friction and wear under dry contact sliding conditions (wheel-rail, overhead contact systems of electric trains, etc)
Tribometers have traditionally relied upon estimations of heat generated from friction and wear of different surfaces.
UNSW is seeking a commercial partner to licence and/or to work collaboratively with the inventors.
