BENCH FOR LOW-CYCLE DEFORMATION-FORCE TESTS OF MODELS OF FULL-SIZE VESSEL STRUCTURES Russian patent published in 2013 - IPC G01N3/12 

FIELD: testing equipment.

SUBSTANCE: bench comprises a body, a lower support, nozzles, a loading mechanism. The body is a reduced mode of an investigated vessel with a nozzle unit made of a socket and a shell, and the loading mechanism is a pump connected to the nozzle of liquid supply via a piston hydraulic cylinder. The nozzle unit is equipped with three resistive strain sensors connected to a strain station and installed one onto the outer surface of the shell at the distance of 3-5 mm from a welded joint, the second one - on the inner surface of the nozzle, in the point of crossing of generating inner surfaces of the shell and the socket, and the third one - on the inner end of the nozzle. There are pressure gauges installed on the body and on the pump.

EFFECT: valid assessment of actual load of equipment, reduced error of strength and resource assessment of vessels and devices, direct testing of which is difficult or even impossible since they are in operation, and testing of their full-size structures has high labour intensiveness.
