Abstract
A method for determining the static friction coefficient of a shoe sole (2) using a test bed (1) comprising a measuring surface (3) with known friction features; a bearing member (4) producing a bearing force Fz on the sole (2); and a traction member (5) capable of generating a movement between the sole (2) and the measuring surface (3); said method comprising the following steps: positioning at least one portion of a sole (2) to be tested on the measuring surface (3); applying a bearing force Fz on the sole (2); gradually causing a movement to be applied to the traction member (5); recording the values of Fx and Fz; and determining the static friction coefficient Mu.
