VIBRATION EXCITER WITH COMPENSATION OF LOAD Russian patent published in 2018 - IPC G01M7/02 G01P21/00 G01V13/00 

FIELD: instrument engineering.

SUBSTANCE: invention relates to a vibrational exciter with load compensation for dynamic excitation of a test sample. Device includes a base, an actuator, armature with the possibility of movement relative to the base, conducted through a linear control means parallel to the direction of the excitation pulses, and a pneumatic load compensating means compensating for at least the gravity of the reinforcement and the test sample. Linear control means of the exciter with load compensation includes an aerostatic bearing, and the load balancing means includes a linear control means.

EFFECT: creation of a compact oscillator that produces a high-quality sinusoidal excitation signal with a small amount of interference by minimizing the emerging when compensating for the friction load and other non-linearities, and when balancing the load to minimize friction and other non-linearity, and without restrictions on the compensation of the load, the forces of gravity are provided both by the vibration displacement and by the force necessary for exciting the oscillations in both directions of the pulses.
