STAND FOR TESTING OBJECTS FOR VIBRO-IMPACT INFLUENCES Russian patent published in 2023 - IPC G01M7/08 

FIELD: test equipment.

SUBSTANCE: invention relates to test equipment, in particular to stands for testing products for impact vibroimpact loads. The device contains a table for fixing the TO, installed in the central part of the elastic shock-absorbing element connected to the stand base, a means for creating a shock load in the form of a falling load placed on the guides, on which a traverse is installed with the possibility of free movement and fixation in a given position, to which the upper end an additional shock-absorbing elastic element is suspended, the lower end connected to the falling load. The elastic shock-absorbing element for installing the TO is made in the form of four strips, the ends of which are symmetrically pivotally connected to the opposite vertical posts of the stand base frame, their middle part is pivotally connected to the table hanging on them coaxially with the axis of the stand, the lower part of the table is rigidly connected to the TO. On the upper part of the table, a vibro-impact loading former is rigidly fixed, containing a vertical rod, on which horizontal beams of different lengths and sections are rigidly fixed, on each of which loads of different masses are rigidly fixed symmetrically relative to the rod. A tubular damper can be put on each horizontal beam between the load and the rod using a threaded connection. A crasher is installed on the top of the vertical rod.

EFFECT: ensuring the possibility of regulating the parameters of the vibroimpact load on the test object.
