Test-rig for the determination of coefficients of sliding friction under the influence of abrasive intermediate materials

This article describes the development of a test-rig in which these parameters can be investigated under realistic simulated conditions, taking into account the effect of various abrasive materials.

The tracked drives of earthmoving vehicles are subject to high levels of wear due to the abrasive nature of the working material. This results in very high costs for spare parts which, over the machine's complete service life, can equal its replacement cost. Before attempts can be made to reduce the wear in the tracked drive, it is important to experimentally determine the tribological parameters affecting the system.

This article describes the development of a test-rig in which these parameters can be investigated under realistic simulated conditions, taking into account the effect of various abrasive materials. The method includes an interesting application of force and measurement transducers.
