DEVICE FOR fatigue tests sample material for impact bending and bending with torsion

摘要

Device for fatigue test samples materials impact strength and flexural-torsional comprising a base mounted on a base rotatable platform mounted radially on the passive sample capture platform arranged on opposite sides of the two blocks of the platform, fixed by means of an axis on the base, covering blocks two flexible rod, one end of each of which is associated with the platform, as well as two groups of goods, serially coupled to each other and to another end of a respective flexible r Yagi in each group, return mechanism platform to the initial position as mentioned cargo groups nagruzhatel a toothed rack mounted on the base with the possibility of reciprocating and interacting with an active capture of the sample and a pair of sector gears kinematically connected to a rotary drive, with periodic and alternating engagement with the rack, characterized in that the platform is made rod-shaped specimen to the head passive capture using two nuts fastened snarling g, the top of the rod on both sides are made the two slots allowing the lever with head passive capture povorachivtsya about its axis in one and the other direction, an active grip is not freely rotatable about its axis, is further placed on opposite sides of the free end of the arm two blocks embodied by an axis on the base, two flexible covering blocks traction, one end of each of which is associated lever as well as two groups of goods, serially coupled to each other and to another
