FIELD: test equipment.
SUBSTANCE: device relates to testing equipment, can be used for fatigue testing of specimens of sheet materials in bending. Proposed plant comprises oscillation source, specimen clamps and measuring device. Source of oscillations is made in form of three-phase electrodynamic vibrator connected to AC frequency converter, and the measuring device is a displacement sensor installed in the console root, the apparatus is equipped with a calibrated load fixed on the free end of the sample.
EFFECT: possibility to increase efficiency and reliability of tests, to provide simple circuit of application of external load, performance of fatigue tests at bending of samples of arbitrary dimensions, non-destructive testing and possibility of loading mode parameters adjustment, such as cycle asymmetry coefficient and external load application frequency.
