FIELD: investigating or analyzing materials by mechanical methods. ^ SUBSTANCE: device comprises base, holder for specimen mounted on the base, carriage with holder for counter-body, loading unit, meter of friction force, drive for moving one of the holders, guide secured to the carriage perpendicular to the surface of the specimen, rod that can be set in translational motion in the guide, loading unit mounted at one of the ends of the rod, pivot mounted at the other end of the rod, holder made of a rod whose one end is secured to the axle of the pivot and the other end is provided with counter-body, spring, meter of friction force mounted on the carriage oppositely from both sides of the holder of counter-body and parallel to the plane of the specimen at the same distance from the axis of the pivot to the working surface of the specimen. The spring locks the holder of counter-body perpendicular to the working plane of the specimen. The axis of rocking of the pivot is parallel to the surface of the specimen and perpendicular to the direction of movement of the specimen and counter-body. ^ EFFECT: expanded functional capabilities. ^ 1 cl, 1 dwg |
