DEVICE FOR TESTING STRENGTH OF VANED DISC OF ROTOR-DYNAMIC MACHINE WITH FORK LINK Russian patent published in 2016 - IPC G01M13/00 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, in particular, to devices for testing the strength of blade discs of rotor-dynamic machines with a fork link. Device comprises a rods intended for connection with grips of the testing machine and with an element of the disk rim by means of rivets designed for placement in mounting openings of the disk rim element, four strips - upper and lower, horizontally located parallel to each other, right and left ones, arranged vertically in parallel to each other and perpendicular to the top and bottom strips, at that, the upper strip comprises five holes, evenly spaced, the bottom, right and left strips comprise three holes evenly spaced, at that, the openings located to the right and left of the central opening of the upper strip and central openings of the bottom, right and left strips are designed for connection and transmission of forces from the respective grips of the biaxial testing machine.

EFFECT: technical result is the creation of operational loading conditions both in the top three mounting holes of the disk rim elements.
