OLIGOCYCLIC FATIGUE OR OLIGOCYCLIC AND POLYCYCLIC FATIGUE TEST RIG Russian patent published in 2018 - IPC G01N3/32 G01N3/04 

FIELD: test equipment.

SUBSTANCE: invention relates to a bench for testing oligocyclic fatigue and, possibly, a combined oligocyclic and polycyclic fatigue to reproduce the support of gas turbine engine parts, such as supporting at least one blade leg on the support neck of the rotor disk cell. Test rig (100) for tests for oligocyclic fatigue and, possibly, on combined oligocyclic and polycyclic fatigue for reproduction of the support of gas turbine engine parts, comprising support member (126) fixed to the structure (108) and forming at least one bearing surface (148), and sample (110) connected to traction means (104) to bring the sample in the position of bearing on the bearing surface or each bearing surface of the device, the bearing surface or each bearing surface (148) being formed on element (136), rotatable about first axis (B) on the support member, and the sample is connected to the tension means by means of the articulation means (114) about second axis (A), substantially perpendicular to the first axis, the bench further comprising means for adjusting and locking the member and the sample in positions around the aforementioned axes.

EFFECT: technical result: finding a simple, effective and economical solution.
