    摘要: A tribological test apparatus (1) has a supporting structure (2), to which are fitted a central shaft (21) rotating about a respective axis (3), and three peripheral shafts (52) rotating about respective axes (54) equally spaced angularly about the axis (3) of the central shaft (21); the central shaft (21) and peripheral shafts (52) respectively support a central specimen (41) and three peripheral specimens (51) facing one another radially; and the apparatus (1) has three actuators (80), each for exerting on a relative peripheral specimen (51) a force (F) directed towards the central specimen (41), and a guide and slide device (56) associated with each peripheral shaft (52) to enable each peripheral specimen (51), in use, to translate radially towards the central specimen (41) and exert a contact pressure on the central specimen (41) by virtue of the force (F) generated by the relative actuator (80).
