REVERSER FOR INVESTIGATION OF PHYSICAL AND MECHANICAL PROPERTIES OF SPECIMENS

摘要

FIELD: test equipment.SUBSTANCE: invention relates to test equipment, and namely to devices for determination of physical and mechanical properties of specimens. A reverser includes external and internal traverses with holes, which are connected in pairs by means of guide columns, a power stock and two connecting bushings installed in holes of traverses and connected to external traverses. In addition, a guide traverse with a hole made in the centre for the power stock is installed between internal traverses on guide columns of fixed traverses. A flat element made in the form of a three-beam star is fixed on the power stock. The power stock has the possibility of being replaced and connected to the flat element. Above internal fixed traverse and under internal movable traverse there arranged are T-shaped platforms rigidly attached to them. A bench support for a test specimen is fixed in the centre of the T-shaped platform of the fixed internal traverse; a heating element thermally insulated from traverses is installed on the same platform. A ball for self-alignment of the power stock and the flat element is rigidly fixed from below in the T-shaped platform of the movable internal traverse. On lower surface of the fixed internal traverse there rigidly fixed under beams of the flat element are three- L-shaped holders with movement sensors installed on them.EFFECT: enlarging functional capabilities of a reverser due to possible investigations of physical and mechanical properties of specimens from any material at the temperature above room temperature.4 cl, 5 dwg
