Abstract
A tribological test apparatus has a supporting structure, to which are fitted a central shaft rotating about a respective axis, and three peripheral shafts rotating about respective axes equally spaced angularly about the axis of the central shaft; the central shaft and peripheral shafts respectively support a central specimen and three peripheral specimens facing one another radially; and the apparatus has three actuators, each for exerting on a relative peripheral specimen a force directed towards the central specimen, and a guide and slide device associated with each peripheral shaft to enable each peripheral specimen, in use, to translate radially towards the central specimen and exert a contact pressure on the central specimen by virtue of the force generated by the relative actuator.
