FIELD: test equipment.
SUBSTANCE: device for testing samples of materials at repeated excitation of damped oscillations contains the base, active and passive grips for the sample mounted on it, the traverse for fixing the active grip, the traverse for fixing the passive grip, the traverse clamps on the base, the elastic element, connected to the traverse for fastening the active grip, the load, connected to the elastic element, the hinged torque link, one link of which is designed with ability to interact with the load, and two pullers for the links of the torque link rotation. The device is additionally equipped with the puller, connected to the traverse to fix the passive grip, and the pullers for the links of the torque link rotation are installed oppositely. The device provides research, both with repeated excitation of the damped oscillations, and with preloading and unloading with load changes parameters control during the tests.
EFFECT: increase of the information volume, obtained during the researches.
