FIELD: testing technique. SUBSTANCE: centrifugal testing bed for samples of materials includes a base, supporting a platform with rotation drive, clamping units for a sample, one of these units, rigidly secured to the platform, embraces one end of the sample; two weights, rigidly joined one with another and having a drive for their radial motion, and apparatus for providing variable-sign bending load. A apparatus for providing torque load is in the form of a rotary face with guides, whose rotation axis is spaced from a rotation axis of the platform. The weights are placed in the guides of the rotary face chuck with possibility of counter-phase motion relative to the axis of its rotation. A mechanism for transmitting a bending load from the face chuck to the sample is in the form of an aperture plate, secured to ends of the face chuck, symmetrically relative to its rotation axis, second clamping unit, formed by two fingers, arranged in openings of the plate symmetrically relative to a straight line, passing through the rotation axis of the face chuck and being normal to its longitudinal axis, and two limiters of an angular position of the face chuck, mounted on the platform. A free end of the sample is arranged between the fingers. EFFECT: simplified structure of the bed. 1 cl, 2 dwg
