Laboratory complex for studying the quality of materials using spectral analysis of signals

Abstract

Abstract The article describes the process of development and testing of a laboratory complex for spectral analysis of measured data, which is based on a signal processing method based on measuring the frequency and amplitude of the signal (spectral method) with further evaluation using fast Fourier transform. The described laboratory complex consists of a spectrum analyzer connected to a personal computer with special software installed on it, a loudspeaker and a laser sensor. The paper substantiates the relevance of the development, due to the fairly wide use of spectral analysis methods in science, technology and production, the advantages of using a laboratory complex in comparison with analogues were shown. There is a description of the experiments to measure the speed of objects, control their location, vibration measurement. The procedure of verification and calibration is performed with the use of this complex, as well as the use of the system of automatic regulation and stabilization of production processes and the training of laboratory works for students of different directions of training in technical and economic specialties.
