Description

one

The invention relates to mechanical measurements and pre-identification values 1 1 (1 for measuring the force under the conditions of the same 1 and compression at a variable length | 1).

Knowledge of ycTpoiicTBa for dklampko graduation dynamas meters, in the cots; r-lh there is no stabilization of oscillations of sp: the s are relative to the hull mappgny, which allows both masses to sovpritt oscillations odiovremeino (syncro | H H0) relative to the body, and therefore, results in: to iogrepyusti gradirovapi dynamometers.

The proposed device differs from the known ones in that, for the purpose of calibration, the excitation electromagnet is installed between the elements of the ynipyroro element connected along the edges through the corlus.

The drawing shows the scheme of the on-board device.

The diammeter 1 is at the end of L1Acc 2, and the other is for the platform of the elastic element 3. The second platform of the elastic element 3 (springs) is connected with the mass of the dynamometer 1 and the mass of the mass 2. Hurray VNS1ven1I v1N: i ) is produced so that, when oscillating .jacc in antiphases, the axis of symmetry is located at the center of the elastic element 3 (spring). The mass 4 and the stiffness of the element are chosen in such a way that the oscillation frequency i ncreMi i

is equal to / iaci) the frequency of the variable is amplified, and the measurement is measured. In order to support the masses, a very fine line of 5 is associated with the logic of machine 6.

Excitement; Ien1: e of the system is carried out electrically: help 7. n (: put ;; in the center of the elastic element. From sensor 8, the signal is fed to amplifier 9. and then to electromagnet 7. Amilitude of oscillation and Г1 is measured by microscope 10 .

Ustr01 1stvs, works as follows. This system 1a of inertial masses is balanced by one center of the elastic element 3, H electromagnet 7 automatically excites; 1, the mass oscillations only in P; rotivophase. At the expense of the sensor; 1ka 8 and the amplifier 9, the electromagnet 7 generates an excitation force, mei., According to harmonic law with a frequency equal to the frequency of the oscillating system. The oscillation takes place in the mode. The iric electromagnet works only to replenish energy losses in the system.

Since the electromagnet 7 causes oscillations in the typhoid relative to the vertical axis of the xyral elsms, gga 3. it is fixed; n: e nos.- sl :: e1H) on the body of the manlina 6, stabilize; About the system relative to the body, i.e., excludes the possibility of the occurrence of other forms of oscillation (for example, synchronous mixing of masses is impossible). Consequences),. Microscope 10, -inqxMi 1s.m (located on the housing of the -shimmy, fixes the amigram of the oscillation, which corresponds to the iicpi; -Mype of force, applied to the diameter.

The force of inertia applied to (1 frame is determined by the lio known formula:

where f is the frequency of oscillation of mass, oed.e1 and -m from the recording of the signal of the o-sensor 8 on the oscilloscope's zaiziuyu1er ();

t is the mass of the load;
