FIELD: physics, tests. ^ SUBSTANCE: invention is related to testing equipment, to strength tests of rock and other material samples and items. Test bench for material fatigue tests comprises base, sample grippers installed on it, device for static load connected to one of grippers, mechanism of cyclic load, comprising pusher for interaction with other gripper, axis, two and more disks installed on axis, fixators for connection of disks with axis, drive of axis rotation. Besides on external surface of disks there are thrusts with the possibility of interaction with pusher, moreover, fixators are installed on each appropriate disk with the possibility of independent switch-over, and number and size of thrusts are selected in accordance with number of peaks and amplitude of peaks in each cycle. ^ EFFECT: higher information value of material survey, and also expansion of parametre control possibility. ^ 2 cl, 2 dwg |
