FIELD: test equipment.SUBSTANCE: invention relates to test equipment, specifically to equipment for testing samples and fragments of spatial box (welded, glued, riveted or glued-riveted) structures. Device comprises a housing accommodating a drive and rigidly fixed therein a metal frame with a base, grippers for test specimen and strain gauges. One of grippers is rigidly fixed on frame, and second one is installed on base by means of two pneumatic cylinders to apply vertical load and torque on test specimen. Strain gauges are arranged on movable gripper and test specimen.EFFECT: technical result is spatial test box-like structures, made by welding, gluing, riveting or gluing-riveting, enabling to perform evaluation of strength characteristics of design in various zones.1 cl, 2 dwg |
