DEVICE FOR TESTING SAMPLES OF MATERIALS AT CYCLIC LOADING Russian patent published in 2014 - IPC G01N3/32 

FIELD: test equipment.

SUBSTANCE: invention belongs to test equipment, namely to devices for assessment of energy of destruction of materials by bend, intensity of material wear, greasing ability of oils and lubricants. The device contains a bed, a pendulum with a weight, a capture fixed on a pendulum for the first sample, a clamp for pendulum latching in the set starting position, distinct from position of balance. The device is supplied with a sensor of control of pendulum movement, connected to a computer, a flexible element fixed on a carriage, a bed installed on the lower part, and a supplied device of its tension, a capture for the second sample, installed in the top part of a bed, thus the pendulum is rigidly connected to a bed through the second sample.

EFFECT: increase in volume of information when loading sample by cyclic loadings with change of loading force, and also complex assessment of energy of material samples destruction on a bend and (or) intensity of wear, greasing ability of media by value of potential energy of a pendulum.
