FIELD: testing equipment.;SUBSTANCE: bench comprises a support frame, a grip for a sample and a grip for a countersample placed in it, a hydraulic mechanism of mutual pressing of samples connected to the sample grip, a hydraulic mechanism of mutual displacement of samples connected with the countersample grip, an energy accumulator connected to hydraulic mechanisms and made in the form of a hydraulic cylinder, a piston placed in the hydraulic cylinder, a fixator of piston position in the hydraulic cylinder, and a hydraulic source of pressure of working medium, connected with the under-piston cavity of the accumulator. The bench is equipped with two pneumatic sources of pressure of working medium, an additional energy accumulator made in the form of a hydraulic cylinder, a piston placed in the hydraulic cylinder, and a fixator of piston position in the hydraulic cylinder, and an additional hydraulic source of pressure of working medium. At the same time hydraulic sources of pressure of working medium are connected with under-piston cavities of appropriate accumulators, pneumatic sources of pressure of working medium are connected to above-piston cavities of appropriate accumulators, and each accumulator is connected with the appropriate hydraulic mechanism.;EFFECT: increased volume of information by provision of tests under wider possibilities of variation in process of experiment of energy volumes and stiffness of loading mechanisms of pressing and shifting of samples.;2 cl, 1 dwg
