TEST SETUP FOR DYNAMIC RUPTURE OF METAL SPECIMENS Russian patent published in 2022 - IPC G01N3/313 

FIELD: samples testing installations.

SUBSTANCE: invention relates to installations for testing samples of pipe steel for rupture. The installation includes base and accelerating plates, grippers, with which the test sample is rigidly attached to the plates, a device for static loading of the sample, which is used as hydraulic jacks, and a device for dynamic loading of the sample. As a device for dynamic loading of the sample, pneumatic cylinders with pistons are used, the working volumes of which are filled with a combustible gas mixture, a bumper is attached to the accelerating plate with the help of racks, with the possibility of moving the plate and the bumper along these racks, at the ends of which, on the side of the bumper, plastically deformable pipes are installed , in addition, for the rigidity of the connection, a mounting plate for pneumatic cylinders and a mounting plate for hydraulic jacks are included. The installation is placed on rails with the possibility of free axial movement.

EFFECT: expanding the functionality of the testing machine.
