TEST-STAND TO ANALYSE CHARACTERISTICS OF DEVICES EXCITING VIBRATION OSCILLATIONS

FIELD: physics, tests. ^ SUBSTANCE: invention relates to test equipment and can be used for producing test-stands designed to measure amplitude-frequency characteristics of the devices exciting vibration oscillations. The proposed device consists of a vibrator comprising a casing with two unbalanced masses on shafts. The said casing is spring-loaded by power and additional springs resting upon the posts. The casing is in contact with the base arranged on the plate over a spherical surface. The power sprigs are arranged in the plane of symmetry of unbalanced masses, while the additional springs are fitted in pairs in symmetry with the plane of symmetry of unbalanced masses. To measure the vibrator amplitude-frequency characteristics, displacement pick-ups are located at the casing corners in pairs and in symmetry relative to the plane of symmetry of unbalanced masses. ^ EFFECT: higher accuracy of measurements. ^ 2 dwg
