Precision Friction Measurement Apparatus- Engineering Lab Training Systems.
Technical Description
The precision measuring unit is used
to determine coefficients of friction experimentally. Several different
pairs of materials with varying surface finishes can be investigated.
During this process, the specimen under examination is stationary and
the supporting friction surface is pulled past it. In this way a stable
force measurement is made over the measuring range 0...2N with a
resolution of 0.05N. The force dial gauge is equipped with an air damper
to compensate slip-slap effects to a large degree. The supporting
friction surface is driven using an electrical synchronous motor. The
drive provides two constant speeds. The normal force can be changed by
adding weights. The sturdy benchtop unit was specially designed as a
student experiment.
