FIELD: testing equipment. ^ SUBSTANCE: invention is related to testing equipment, to strength tests. Installation for fatigue tests of material samples comprises body, three racks arranged in it, two of which are parallel to each other, and the third is perpendicular to it, geared wheel that connects the third rack to one of two parallel racks, mechanism of reciprocal motion, which interacts to end of the third rack, torque link, central hinge of which is connected to body, and end hinges are connected to parallel racks. Also two gear reducers are installed on body, which are intended for alternate connection of parallel racks to each other. At the same time one reducer consists of two joined wheels, the other reducer consists of three serially joined wheels. Moreover, depending on selected mode of samples interaction, reducer of two or three serially joined wheels are installed. ^ EFFECT: increased volume of produced information in mode of samples interaction in process of bending with identical or different signs of axial load. ^ 1 dwg |
