Description
The coefficient of friction is measured at the contact points of two materials: – thread (or wire) against solid bodies such as ceramic or metal. Any friction body shape can be used, round friction bodies in a diameter range from 2mm to 60mm. With the thread/thread friction coefficient measurement, the thread is wrapped around itself and thus forms a friction body at the points of contact.
Options:
RK-FHS200: Friction coefficient measurement on heated ceramic and steel friction elements
RK-SS26: Stick-slip measurement (static friction measurement)
Adhesive friction measurements are carried out at a slow thread speed (approx. 1 mm/min). At this speed, a steadily increasing tensile force builds up in the test material after it has passed the friction body. This tensile force drops abruptly when the test material comes into sliding friction (slip). The amount of tensile force that builds up is a measure of the static friction. The low speed is generated by the pull-off device and displayed digitally. The same transducers and measuring arrangements are used as for friction measurement.
Evaluation via PC
The evaluation of a friction coefficient µ measurement is carried out using the RK-WIN software.
It provides a graphical representation of the measurement process, a measurement log and much more.
The software package also includes a USB interface.
