Abstract

The invention relates to a measurement technique and makes it possible to increase the accuracy and reliability of indications by reducing the effect of accelerations. For this purpose, a counterweight 9 is mounted on the tiller 3 of the device with the possibility of movement along the tiller's axis. When the position of the moving object changes, the center of gravity of the system is a weight (jumper 4 and a permanent magnet 5) - the counterweight is in the axis of rotation, and the oscillations of the free-motion ball 7 located in the damper tube 6 are extinguished by a viscous liquid 8, which makes this system is insensitive to acceleration. Due to the fact that the deviation angle of the tang is larger than the angle of inclination of the moving object, there is no need for a large gain factor of the electromechanical transducer 2 angles n of the measuring circuit 1. 2 I.L. {I ate about 00 cd 0 Go 8

Description

The invention relates to a measurement technique, in particular, to devices for determining tilt angles of moving objects, and is an improvement of the known device described in the ed. St. No. 777423.

The aim of the invention is to improve the accuracy and reliability of indications by reducing the effect of accelerations.

FIG. 1 shows a diagram of the device; in fig. 2 - the same, with an oblique position of the object.

The device contains a measuring circuit 1, an electromechanical angle transducer 2 (selsyn, a rotating transformer) into an electrical quantity, a measuring tip 3 rigidly connected to the rotary axis of the transducer 2, a load consisting of jumper 4 and permanent magnets 5, a damper 6, made of a diamagnetic material in the form of a tube, the shape of which corresponds to the arc of the ellipse with the center aligned with the axis of the transducer. Inside the tube 6 there is a free-moving ball 7. The cavity of the damper is filled with a viscous liquid 8. A counterweight 9 is mounted on the master, whose displacement along the axis of the pilot is adjusted by means of a micrometer screw 10.

The device works as follows.

In the static mode (the speed of the objective scheme, resulting in a constant device), when the stabilized position of the moving self-propelled device changes and as the angle of inclination appears, the device body is rotated at the same angle together with the stator of the Electromechanical converter 2 and the cavity 35 rigidly connected to the housing of the device. At the same time, the tandem 3 with the load (jumper 4 and magnets 5) and the counterweight 9 tends to occupy such a position that the line passing through the axis of rotation and center of gravity of this system is vertical, and the center of gravity is lower than the axis rotation When the center of gravity is in the axis of rotation, the system is in a state of indifferent equilibrium and due to the magnetic interaction of the magnets 5 and the ball 7, it follows a freely moving ball, which tends to the lowest point of the damper cavity. This point is determined by the horizontalness of the arc tangent damp40

The tool for determining tilt angles becomes less sensitive to small fluctuations of the mixer with the free-moving body in the dynamic mode.

Invention Formula A device for determining the angle of inclination of a moving object j according to the ed. St. No. 777423, characterized in that, in order to increase the accuracy and reliability of the readings by reducing the effect of accelerations, the master is equipped with a counterweight adapted to move along the axis of the antenna, the tube of diamagnetic material is filled with a viscous liquid and made in the form of an ellipse arc, the center which is combined with the axis of rotation of the tiger, and the free-motion body is made in the form of a single ball. FERA (FIG. 2). The angular coefficient of the tangent of the ellipse is defined as tgot -K.-y-, and the angular coefficient of the tangent to a circle of radius OM is tg, where K is the compression ratio of the ellipse; X, y - coordinates. Thus, the tangent of the deviation angle of the model in the proposed device, when the center of gravity of the system in the axis of rotation is 1 / K, is greater than the tangent of the angle of inclination of the moving object. The magnitude of the rotation angle of the rotor, which is rigidly connected to the rim, is converted into an electrical signal supplied to the measuring circuit 1. In dynamic mode (object speed is not constant) when the position of a moving self-propelled device changes and the angle of inclination is observed, the tilt-counterweight system is insensitive to acceleration, since its center of gravity is in the axis of rotation, and the oscillation of the freely movable ground TC viscous liquid filling the damper and inertness of the master-load-counterweight system. Due to the fact that the deviation angle of the tiller is larger than the tilt angle of the moving object, the need for a large gain coefficient of the electromechanical transducer disappears and the electrical matter for determining tilt angles becomes less sensitive to small tilts of the free-moving-body model in the dynamic mode. Invention Formula A device for determining the angle of inclination of a moving object j according to the author St. No. 777423, characterized in that, in order to increase the accuracy and reliability of the readings by reducing the effect of accelerations, the master is equipped with a counterweight adapted to move along the axis of the antenna, the tube of diamagnetic material is filled with a viscous liquid and made in the form of an ellipse arc, the center which is combined with the axis of rotation of the tiger, and the free-motion body is made in the form of a single ball. / / / Bepfnuf a b (rig. 2
