Description

(54) DEVICE FOR MEASURING THE REALITY OF VIBRATION SYSTEMS

 The invention relates to the field of measurement technology and can be used for tuning electronic equipment, monitoring technological processes, measuring parameters of electrical and mechanical systems. Devices are known for measuring the effective quality factor of oscillatory JCB systems containing a full-wave input rectifier and two threshold channels consisting of threshold elements, integrative peppies, an anti-coincidence circuit, a saw head voltage indicator and indicator: However, these devices do not provide practical accuracy direct reading of the current quality in the frequency range of damped oscillations. The purpose of the invention is to provide a direct reading of the value of the quality factor and improve the measurement accuracy in the frequency range of input damped oscillations. This is achieved by introducing a meter for the frequency of damped oscillations, a frequency multiplier and a setup-to-measure switch. The tuning body of the frequency meter is mechanically coupled to the frequency multiplier. The input of the frequency meter is connected to the input of the full-wave rectifier, the input of the frequency multiplier is connected to the output of the sawtooth, and the output indicator through the switch is connected to the output of the frequency meter and the output of the frequency multiplier. FIG. 1 shows a block diagram of the proposed device; in fig. 2 - time diagrams of his work. The device contains a source of damped oscillations 1, a full-wave rectifier 2, threshold devices 3-6, in-. tagging chains 7 and B, anti-coincidence circuits 9, forma- tion of sawtooth 11 arrays 10, frequency multiplier 11, frequency meter 12, tuning-measurement switch 13 and output meter 14.

The device operates in two stages: the stage (mode) settings and the stage (mode) of the purpose set using switch 13, which connects the measurement of output 14, respectively, to the MW position

When tuning the frequency meter 12 to its output with the help of the switch 13, the output meter 14 is connected, the frequency multiplier 11 is set to the position at which it is running (see

FIG. 1 and 2, the point k) is ensured by the projection of the ratio between the input amplitude | and the measured quality factor.

During the measurement operation, the indicator you.: Stroke 14 with the switch 13 is connected to the output of the multiplier 11 and the value of the quality factor is read by the indicator.
