TEST BENCH FOR VIBRATION TEST OF BACK SIGHT Russian patent published in 2015 - IPC G01M7/02 

FIELD: test equipment.

SUBSTANCE: test bench for vibration test of a back sight contains a vibration exciter with a table, the device for placement of the tested product having a shape of cube with a cover which is rigidly fastened to the table of the vibration exciter. On external surfaces of the cube windows for electric sockets, the back sight lens, and stiffening ribs are made, in the top part of the cube two guides with grooves are located, with form a truncated prism, the cube cover is designed as a plate - the object simulator to which the back sight is fixed, and there is a ledge interacting with grooves of the guides. In the specific case for restriction of longitudinal movements and forces acting on plate fasteners - the object simulator, the contacting surfaces of the plate holes - the object simulator and fasteners are made with the cone slope, equal to 2.

EFFECT: improvement of accuracy of measurement of vibrotransfer overloads in the required range of frequencies of a back sight by increase of rigidity of a test bench structure.
