Friction characterization test systems have dual-purpose function, where they could be used as equipment for qualifying the manufacturing process through quality inspection, or for material development. For the purpose of objective quality inspection, these machines are utilized to evaluate acceptable product tolerances and consistency within part production from material batch-to-batch variation. With respect to material development, these machines are precisely utilized to evaluate frictional properties and effect of individual raw material ingredients.
Some common friction material characterization test stands include:
Quality testing consists of conducting a baseline test and comparing tests of identical samples in search of any variation outside of the allowable deviation. Development testing consists of conducting a baseline test with subsequent samples modified as such to perform a design of experiments to understand cause and effect of material or process modification.
Material can also be certified to meet industry standards on such equipment as the Link Chase machine. In the 1940’s, Link collaborated with General Motors to develop the Chase machine as a method to assess friction material characteristics.
Measurement systems and engineering methods within the mechanics of these machines are strictly evaluated to eliminate potential sources of test variability. Typical test measurements include compressibility and coefficient of friction and may be expanded further to include thermal and wear characteristics.
