CENTRIFUGAL PLANT FOR MATERIAL SAMPLE STRENGTH TESTING Russian patent published in 2014 - IPC G01N3/12 

FIELD: testing equipment.

SUBSTANCE: centrifugal plant comprises a body, a shaft installed on it with a rotation drive, a hydraulic cylinder fixed on the shaft perpendicularly to its axis, a piston placed in the hydraulic cylinder, as well as a fixator of piston position in the hydraulic cylinder, a grip for connection with the sample end, fixed on the piston in the under-piston cavity, and a source of medium connected to the under-piston cavity of the hydraulic cylinder by means of an input hole in the hydraulic cylinder. The source of medium is made in the form of the second hydraulic cylinder with the piston and the stem, filled by the medium and connected to the inlet hole of the first hydraulic cylinder, and a mechanism of reciprocal movement of the stem, at the same time the medium is liquid or gas.

EFFECT: expansion of functional capabilities of a plant by testing both under permanent and cyclic volume or flat loading with uneven distribution of load and with displacement of a loading zone along length of the sample with provision of transitions from loading by stretching mass loads to loading by pressing mass loads and with adjustment of the value of zone of uneven load distribution spread along sample length in process of testing.
