STAND FOR TESTING ARTICLES ON COMBINED EFFECT OF VIBRATION AND LINEAR ACCELERATIONS Russian patent published in 2010 - IPC G01M7/02 

FIELD: physics.

SUBSTANCE: stand has a centrifuge which has an electric drive, a rotor and a device for transmitting rotation of the vertical shaft of the drive to the rotor, made in form of an elastic clutch consisting of a driving and at least one driven half-clutch connected by an elastic coupling, as well as a disc, mounted on a rod which is coaxially attached to the shaft of the electric drive, and movable supports for mounting test objects on the rotor. The disc is mounted horizontally on the rod and has a dowel fitted vertically at given distance from the axis of the shaft. The rotor is made in form of horizontal guides mounted symmetrically about the axis of the shaft on a bearing frame which is rigidly mounted on at least one driven half-clutch. The movable supports are made with possibility of longitudinal displacement relative the guides and are fitted with detachable elastic suspensions which restrict their displacement relative the guides. Along the guides there are pull rods, each pivotally joined by one end to the corresponding movable support, and by the other end to the dowel. The electric drive is made with possibility of simultaneous transmission of direct and alternating current components to the armature coil of a dc motor.

EFFECT: simple design, possibility of independent control of the level of vibration and linear accelerations, testing heavy articles.
