Abstract

This invention relates to a testing technique. The purpose of the invention is to improve the accuracy of testing by ensuring that a blow is struck at a given point of the structure. The stand contains a base 1 with a stand 2, a device 3 for fastening the test structure 4, a master in the form of a flexible suspension 5 with a striker 6, a mechanism for lifting and releasing the tank, including a barrel 7 and a descender 8. The stand is equipped with two intersecting flexible rods 10 and 11, - a connecting link 12. installed at the point of crossing t g with the possibility of adjusting movement along them, and a load 13 suspended through block 14 to the rack 2 and to the lower end of the rod 10, while the section 16 rod 11 is perpendicular suspension 5 tattoos. Before the tests, the hammer 6 on the vertically mounted suspension 5 is brought to the test structure 4 at the desired point of impact and engages the trigger 8. By moving the connecting link 12 in tams 10 and 11, followed by fixation, a section 16 of the tractor 11 is installed perpendicularly to the suspension 5. After the tilting of the tommy to the required angle, the area of 16 tons of gi 11 remains perpendicular to the suspension 5, not depending on its stretch from the weight of the striker. 4 il. (L
