BENCH FOR VIBRATION RESISTANCE TESTS Russian patent published in 2015 - IPC G01M7/02 

FIELD: test equipment.

SUBSTANCE: invention refers to test equipment and can be applied in various industries for vibration resistance tests in three mutually perpendicular directions. Device includes vibrator with table bearing a fixture for test object fixation. The fixture allows for test object re-orientation and fixation in three mutually perpendicular directions without object dismounting. Fixture case features two mobile frames, one mounted in the other, with mutually perpendicular rotation axes, so that the frames can turn by 90° around the axes, and each frame has a device for locking after re-orientation in the form of disc brake and wedge clamp. Internal frame includes a unit for torque transmission from a drive to the object. Vibrator base features a portal in the form of rack and support, its horizontal beam bearing two rollers on brackets, with roller output shaft pulley connected in series with work pulley of the device for tests in dynamic mode of object.

EFFECT: possible vibration resistance test in three mutually perpendicular directions without object dismounting, enabled testing of articles in static and dynamic modes of the object state.
