DEVICE FOR FASTENING OPERATING FOOT OF TURBO DUMP WITH LOCKING ELEMENT DURING FATIGUE TESTS Russian patent published in 2018 - IPC G01M7/00 F01D5/00 

FIELD: testing equipment; turbines or turbomachines.

SUBSTANCE: invention relates to design of devices for fixing working blades of turbomachine on a shaker table during fatigue tests. Device for fastening working blade of turbomachine with locking element during fatigue tests comprises housing rigidly fixed on vibrating table with the help of bracket, clamp with fixing elements mounted on the housing. Groove is made in the clamp, repeating locking part of the blade. Device is equipped with flexible hose attached to housing with threaded connection. Cavity is made in the case. In the case near the clamp there are holes connecting hollow part with the atmosphere. Fixing elements are located between groove and hollow part of the housing. Clamp consists of two parts, one of which is movable, with the possibility of removal and contains a hook, and the other is part of the body and contains a recess, repeating its form of a hook.

EFFECT: technical result is to reduce effect of temperature tests on the rigidity of device and expand range of materials used for production of its elements.
