FIELD: testing equipment.
SUBSTANCE: plant for physical and mechanical survey of material samples comprises a bed plate, sample grips installed on it and a loading mechanism made in the form of a geared wheel, a gear rack interacting with it and installed as capable of axial displacement and connected to one of the grips, a rod connected with the geared wheel, a lever hingedly installed at the end of the rod, a fixator of lever rotation relative to the rod, and a weight installed on a free end of the lever. At the same time the additional wheels are installed in one plane with the main wheel and are kinematically connected to it. Axes of wheels rotation are arranged on the same line perpendicular to the axis of the rack, at the same time wheels have different diameters. The plant provides for performance of tests in symmetrical or asymmetrical cycles of damped oscillations of the load under new conditions - in case of stepped changes of cycle parameters with transitions from cyclic to permanent loads and back.
EFFECT: expansion of functional capabilities, higher information value of surveys.
