INSTALLATION FOR TESTING SAMPLES OF MATERIALS AT REPEATED EXCITATION OF DAMPED OSCILLATIONS Russian patent published in 2011 - IPC G01N3/34 

FIELD: machine building.

SUBSTANCE: device for testing samples of materials at repeated excitation of damped oscillations consists of base, of crossbeams mounted on it, of two sample grippers secured on corresponding crossbeams, of crossbeam holders on base, of flexible element connected with first crossbeam, of load connected with flexible element, of hinged torque link, one link of which is joined with load, and of pusher for turning links of torque link. Also, the device has an additional flexible element connected to the second crossbeam, an additional load connected to the additional flexible element, an additional hinged torque link, one link of which is coupled with the additional load, an additional pusher for turning the additional torque link, four additional crossbeams and four holders of additional crossbeams on the base. Two additional crossbeams are positioned between the first link of each torque link and corresponding load. The other two additional crossbeams are connected with the second link of each torque link. The flexible elements are of different rigidity, while loads are of different weight.

EFFECT: facilitation of loading with not complete or complete attenuation of oscillations individually in each series.
