FIELD: physics.
SUBSTANCE: stand has a frame, a supporting device in form of coaxial conical gas bearings in a housing, an elastic suspension and a system of sensors. The elastic suspension has a block of elastic plates and two torsion bars. One torsion bar is can be fixed by one end behind the supporting device and the other behind the article. The second torsion bar can change rigidity and is joined to the frame by one end and to the supporting device by the other. On the side of the supporting device, the second torsion bar is fixed on a block of bearings which are joined to the frame by elastic plates. The elastic suspension and the supporting device provide the article with three degrees of freedom - two rotational and one translational. A system of measuring transducers detects displacements, the position and shape of the article in the supporting device, and displacements of the supporting device on the available two degrees of freedom.
EFFECT: high efficiency and accuracy of measurement.
