FIELD: test equipment.
SUBSTANCE: invention relates to test equipment, to devices for testing materials, particularly rock, when testing energy exchange in rock masses in order to forecast and prevent dangerous dynamic phenomena. Test bench comprises a support frame, sample gripping device and counter-sample gripping device, arranged in the support frame, mechanism of mutual sample pressing connected with the sample gripping device, mechanism of mutual displacements of samples, connected with the counter-sample gripping device. Test bench is additionally equipped with additional gripping devices for additional counter-samples, additional mechanisms of mutual displacements of counter-samples, connected to corresponding additional gripping devices for additional counter-samples, retainers for successive connection of additional gripping devices for additional counter-samples to each other and to the sample gripping device, and retainer for connection of the counter-sample gripping device to the base.
EFFECT: technical outcome is increased volume of information by testing the shift along one and more shift planes while changing the number and location of shift planes during tests.
