FIELD: test equipment.SUBSTANCE: invention refers to test equipment, to strength tests. Setup includes a bed carrying sample grips and cyclic load device in the form of cog wheel interacting with mobile rack linked to one of the grips, a bar connected by an end to the cog wheel, and load mounted on the other bar end. In addition, the setup includes second rack linked to the second grip, and shock load devices matching the number of shock momentums, each device in the form of cog wheel interacting with the second rack, arm with rotation axis coaxial to the cog wheel and rotating independently, load mounted on the arm, and two rests mounted on the cog wheel and interacting with the arm, the load is located higher than arm rotation axis, the arm is positioned between the rests with a gap, and the rests on each cog wheel are tilted in comparison to the rests of the other cog wheels.EFFECT: increased information content of material sample tests by superposition of compressing and extending shock momentums on damped load oscillation cycles.2 cl, 1 dwg |
