Tribometer

Tribometer are devices for measuring friction and wear, so of sizes in tribology.

Due to the extremely wide range of issues in tribology tribometer numerous for specific applications and measurement tasks have been developed over the years. The interpretation and transferability of on tribometers ( Laborprüfmaschinen ) obtained results is scientifically challenging. In addition, many tests are not standardized and are not subject to independent round-robin tests. Since it is always to system parameters in tribological characteristics, the specification of single values ​​as coefficients of friction is not effective without specifying the exact test conditions.

Depending on the task to be examined material pairings are rotary ( eg pin / disk tribometer ) or translational burden (eg oscillating friction and wear tester ). Rolling and rolling motions can be simulated, for example, two-disc test rigs. The great advantage of Laborprüfgeräte is that the stress parameters can be varied defined (force, relative velocity, lubrication, temperature, etc. ), which is often not possible in aggregates or field trials.
