BED TESTING ARTICLES FOR EFFECTS OF VARIABLE ACCELERATIONS Russian patent published in 1995 - IPC

FIELD: testing equipment. SUBSTANCE: rotary chuck plate 4 which ends are tied up with pulled flexible cable 17 passed over roller 16 mounted on platform is positioned on periphery of platform 2 equipped with rotational drive. Axis of rotation of roller and axis of turn of chuck plate are parallel to rotational axis of platform. Distances between axes of rotation of chuck plate and roller and axis of rotation of roller and points of attachment of cable to chuck plate are equal. Chuck plate is fitted with reversible drive 5 mounted on platform. Normal components of pulling force of cable applied to ends of chuck plate create bending moment opposite to moment of centrifugal forces. As a result of this bending deformation of chuck plate during operation of bed diminishes. Tested article 9 is anchored on table 7 put on chuck plate for turning. EFFECT: enhanced authenticity of testing. 2 dwg
