Patent ID: 8915117

Claim:
A friction mensuration device, comprising: a force engine configured to apply a tractive force to a wheel-less test piece disposed on a test surface; a controller coupled to the force engine, and imposing a tractive signal to the force engine, a sensed force signal to the controller selectively actuating the force engine to produce the tractive force; and a force sensor coupled between the force engine and the test piece, the force sensor producing the sensed force signal responsive to a sensed force between the force engine and the test piece, wherein the force engine is intrinsically calibrated to the Normal force, wherein the test piece receives the tractive force, wherein the test piece translates the tractive force into a test force applied to one of preselected material samples coupled to the test piece, wherein the test force applied to the one of preselected material samples is representative of a friction force between the one of preselected material samples and the test surface, wherein one another one of the preselected material samples comprises a control sample including a piece of footwear or a resin rubber or a composite material, wherein a sensed force measurement representative of a stiction force is rejected by the controller, and wherein a measurement by the device is reliable, reproducible, verifiable, and operator-independent.
