Tribometer
Tribometers are devices for measuring friction and wear , i.e. variables in tribology .
Due to the extremely diverse issues in tribology, numerous tribometers have been developed over the years for specific applications and measurement tasks. The interpretation and transferability of results obtained on tribometers (laboratory testing machines) is scientifically demanding. In addition, many tests are not standardized and are not subject to independent round robin tests. Since tribological parameters are always system parameters, specifying individual values such as friction values without specifying the exact test conditions is not expedient.
Depending on the task at hand, the material pairings to be examined are loaded rotationally (e.g. pin / disc tribometer) or translationally (e.g. vibration / frictional wear test stand). Rolling and rolling movements can be simulated with two-disc test stands, for example. The great advantage of laboratory testing devices is that the load parameters can be varied in a defined manner (force, relative speed, lubrication, temperature, etc.), which is often not possible in unit or field tests.
