BENCH FOR ANALYSIS OF ENERGY EXCHANGE IN SPECIMENS OF ROCKS Russian patent published in 2015 - IPC G01N3/10 G01N3/24 

FIELD: test hardware.

SUBSTANCE: invention relates to test hardware, particularly, to appliances for testing of rocks in energy exchange processes to forecast and prevent dangerous dynamic phenomena. This bench comprises support frame to support specimen gripper and counter specimen gripper, specimens squeezing hydraulic mechanism, specimens displacement drive engaged with counter specimen gripper, pressure sources connected with squeezing and displacement mechanisms and mechanical energy accumulator with spring arranged between displacement drive and counter specimen gripper. Said mechanical energy accumulator is composed of the guide engaged with counter specimen gripper, pusher composed of hollow cylinder arranged at said guide and engaged with displacement drive. Note here that the spring is arranged at the guide between counter specimen gripper and pusher, plate being laid in sets to face each other by their concaved surfaces. Note here that the number of plates on every side of each set is equal while in different sets it is selected to meet preset stiffness characteristics of accumulator.

EFFECT: increased bulk of data owing to constant and variable stiffness characteristics.
