In this paper an apparatus for investigations on both static and dynamic friction is described. The apparatus is simple but very modular and can be used in two different configurations: (i) controlling the displacement of an upper specimen connected by an elastic wire to a moving load cell; (ii) controlling the displacement of a lower specimen connected to a moving plate. The capabilities of the apparatus are shown through some preliminary tests that also highlight the several factors that can affect the friction coefficient estimation.

Abstract
In this paper an apparatus for investigations on both static and dynamic friction is described. The apparatus is simple but very modular and can be used in two different configurations: (i) controlling the displacement of an upper specimen connected by an elastic wire to a moving load cell; (ii) controlling the displacement of a lower specimen connected to a moving plate. The capabilities of the apparatus are shown through some preliminary tests that also highlight the several factors that can affect the friction coefficient estimation.File in questo prodotto:
