BENCH FOR IMPACT TESTS OF SAMPLES OF MATERIALS Russian patent published in 2016 - IPC G01N3/32 

FIELD: test equipment.

SUBSTANCE: stand includes base, flywheel installed on it with rotary drive rod on number of loading points according to specified specimen surface with hammers for interaction with sample, installed with possibility of changing position along length of flywheel, device for creation of friction interaction of rods with flywheel, appliance for return of rods in initial position and device for location of sample made to allow interaction between sample with hammers. Stand is equipped with additional rods on number of loading points on opposite surface of sample, additional accessories for creation of friction interaction of additional rods with flywheel, additional accessories for return of additional rods in initial position and additional hammers on number of additional rods. Friction interaction of main and additional rods is carried out with sections of surface located on diametrically opposite forming flywheel, additional rods feature L-shape, one side of which is intended for interaction with a flywheel, and other side fixed striker.

EFFECT: increased amount of information when investigating material properties by providing tests at repeated impacts at different points of specimen surface with randomly controlled sequence intervals and points blows not only in one direction, but in opposite direction and simultaneously in opposite directions.
