FIELD: testing equipment.
SUBSTANCE: bench comprises an unloading truss or a power stand, a system of soft suspension or a device for joining of the test object with the power stand, a set of electrodynamic vibrators (EDV), a set of transitional elastic elements for connection of the tested object with movable parts of the EDV, a control and a measurement-computing complex. Additionally it comprises a set of additional weights for installation on movable parts of the EDV, or an additional set of EDV with other masses of movable parts.
EFFECT: higher accuracy of measurements in process of experimental determination of frequencies and generalised mass of a tested object.
