FIELD: testing technology.SUBSTANCE: unit comprises a base, a turntable platform mounted on it, grip of the sample mounted on the platform, two centrifugal weights designed to secure at the ends of the sample, rotary drive of the platform, comprising a shaft with the rotary drive, a pair of rollers mounted eccentrically on opposite sides of the rotation axis of the platform and designed for frictional interaction with it, one of which is mounted on the shaft. The unit is additionally provided with a second shaft mounted coaxially with the first shaft and the rotary drive of the second shaft, at that the second roller is mounted on the second shaft.EFFECT: enhanced functionality of the unit through providing tests both at alternating bending in two planes, and at alternating bending in one plane and constant bending in a second plane, as well as at circular bending and circular bending with stretching.1 dwg |
