BENCH FOR FATIGUE TESTS OF MATERIALS Russian patent published in 2009 - IPC G01N3/34 

FIELD: testing equipment.

SUBSTANCE: invention refers to testing equipment, to fatigue tests of items and specimens of materials. Bench for fatigue test of materials includes base, active and passive grippers installed on it and used for tested object, static loading mechanism attached to passive gripper, pusher connected to active gripper, cam kinematically connected to pusher and located on axis, and cam axis rotation drive. At that, cam is made in the form of ellipse, supports are installed in series between cam and pusher with possibility of being moved along movement direction of pusher and mutual rolling motion along generating surfaces; at that, supports are made in the form of ellipses with various length of main axes; on cam axis there installed is the second cam and fixture of the second cam on axis; at that, the second cam provides displacement of the support nearest to cam along direction of pusher movement.

EFFECT: enlarging functional capabilities of bench by providing tests at asymmetric impulses.
