Description

HaoopCTCiiiie is in the field of measuring technology.

Known angular accelerometers with liquid damping, containing ier.1; | a single mass, strengthened in the housing on the torsion, and strain gauge transducer.

In order to reduce the error in measuring the P1I in the proposed accelerometer, the inertial mass is made in the form of a symmetric body with equal rotation moments relative to any two mutually pericultural axes, which are arranged in a plane, perpendicular sensitization wires, and four wires must be attached to one of the ten wires.

The drawing shows the described accelerometer containing an inertial mass / in the form of a cross with a fixed hollow ring, which is equal to the average density of the inertial mass of the damping fluid. Aiacca 1 inerziopp, using a torsion bar 2 through the top 3 and bottom 4 pillars, connects each other, is attached to the dropout 5. At the ends of the crosses of the cross and on the bottom of the pivot are the pins 6, which are wound with tensile transducers 7 to the bottom. 5 of the accelerometer is attached to the clip 8, on the bottom of which there is a compensator 9, separated from the bottom of the sensing element by a rigid partition 10 with a small hole in the center. In each syringe of the inertial mass / rasiololon, the permanent magnets 11, which belong to their pole B coils 12, are fixed to the base 5 of the accelerometer. The internal volume of the accelerometer is dampened by a damping fluid. When acting on an accelerometer of angular acceleration (11), 1a mass / is rotated relative to the base on an angle, proportional to the effective angular acceleration. In this case, the two opposite arms of the teisometric transducer 7 operate on

compression, t. without them, their size decreases, and two D1) of the upper and lower shoulders work and grow. i.e. their co-motivation to increase. To determine the damping coefficient at iodine selection, the damping fluid 11 to pick up the amplitude phase-frequency characteristics of the terminals of the coils 12 through the accelerometer connector signal from the generator. Using coils 12 by giving the appropriate signal

They check the accelerometer's accelerometer while carrying it on the object.
