Abstract:

System for conducting measurements of friction of a chosen material with reduced errors. The system includes a sample holder, a bushing accommodating such holder while permitting reversible repositioning of the holder along a bushing axis, a horizontal force sensor, a vertical force sensor, a sample holder pusher and a subsystem including a linear vertical bearing (disposed in the bushing and separating the holder from the bushing) and/or a horizontally-sliding element between the rod pusher and the vertical force sensor. The subsystem is structured to reduce a rocking motion of the holder in the bushing caused by a relative motion between the sample and an auxiliary body brought in contact with the sample. The method for performing measurements with such system.
