FIELD: measuring equipment.

SUBSTANCE: invention relates to measuring equipment and can be used to adjust and analyze the accuracy of the operation of a uniaxial power horizontal gyrostabilizer with an imitation of its movement in a turn in laboratory conditions. The installation includes a uniaxial horizontal gyrostabilizer mounted on a turntable (18) and having a gyro unit (1) with a vertical rotor axis in a gimbal, an interframe correction chain, a drive chain and a circuit for simulating the influence of centripetal acceleration. The interframe correction circuit consists of a precession angle sensor (7, 8) connected to the first input of the stabilization amplifier (9), the second input of which is connected to the object's linear velocity sensor, consisting of a tachogenerator (13) and a scaling amplifier (12) that are consecutively connected. The output of the scaling amplifier is connected to a stabilizing motor (10, 11) mounted on the outer axis to which the system angle sensor (16, 17) is kinematically connected. The drive circuit contains a pendulum angle sensor (PAS) (3). Its output is connected to the first input of the correction amplifier (4) connected to the torque sensor (5, 6). The circuit for simulating the influence of centripetal acceleration consists of an angular velocity sensor (19) fixed on a turntable (18) with an input axis parallel to the axis of its rotation, a multiplication unit (20), the output of which is connected to the second input of the correction amplifier (4), while the first input of the multiplication unit is connected to the output of the angular rate sensor (19), and the second input is connected to the output of the tachogenerator (13), which is kinematically connected to the motor (14), to the input of which the linear speed generator (15) is connected. To adjust the compensation circuit, the center of mass of the PAS is set strictly along the axis of rotation of the platform, and the action of centripetal acceleration is simulated by a signal from the tachogenerator and the angular rate sensor. The adjustment is controlled by the signal from the system angle sensor (16, 17).

EFFECT: invention improves accuracy of adjusting the high-speed correction contour in laboratory conditions with less labor intensity.
