ELECTROMECHANICAL VIBRATION TEST STAND Russian patent published in 2011 - IPC G01M7/06 

FIELD: physics.

SUBSTANCE: device is in form of a table which is movably interfaced with a base by guides which facilitate its vertical displacement. The guides of the table are in form of two identical four-link chains of parallelograms, whose planes are parallel to the axis of movement of the table. Similar links of the parallelograms are in form of flexible plates which are yieldable in the direction of movement of the table. The guides are fixed in pairs on the base of the vibration stand such that in the neutral middle position of the table, adjacent flexible links of the parallelograms lie in the horizontal parallel plane of the table. An electric motor with a cam mechanism rests on the table. Constant contact between the table and the cam mechanism is provided by recoil springs. The device also has an actuation and measurement unit, as well as a vibration sensor.

EFFECT: high reliability of test results, reduced equipment wearing.
