GEAR FOR STRENGTH TESTING OF PANELS Russian patent published in 1997 - IPC

FIELD: equipment testing panels of flying vehicles and other structures for strength. SUBSTANCE: proposed gear for strength testing of panels includes rigid frame which carries two systems of compression force loading in mutually perpendicular directions with force-transmitting members and system of shear force loading. Gear is equipped with grippers 10 with grooves in working faces and wedge-shaped protrusions on opposite faces, bearings 11 positioned in of bearing casings 9, duct 12 hinged to panel in one point and resting against panel with the aid of rolling bearings 16 arranged on edges of duct with spacing determined from condition of avoidance of local loss of stability of sheathing between these bearings. Elastic shell 14 tightly attached to panel is put on outer surface of duct. EFFECT: increased operational reliability of gear. 2 dwg
