METHOD OF CARRYING OUT LABORATORY WORK ON THE DETERMINATION OF THE PARAMETERS OF VIBRATIONS IN SAMPLE ALLOYS

Abstract

The article describes the installation of laboratory work on the study of damped oscillations and computer algorithms for determining the parameters of the curve describing the damped oscillations. The algorithms are implemented in the software environment “Origin”. With a few changes, these algorithms can be performed in software environments such as “Excel” or “Matlab”. According to the results of processing the curve of damped oscillations are determined by the dependence of the decreasing amplitude of the oscillations on time and the functions describing the nature of the change: the logarithmic decrement and the damping coefficient on time. According to these data, dependence of the damping coefficient on the amplitude of damped oscillations is constructed, which is important for fundamental physics studying the phenomenon of magnetostriction in alloys, and in particular, in high-damping alloys. The developed algorithms can serve as the basis for laboratory work on the study of weakly attenuating oscillations in the school.
