Soft- and hardware system in devices measuring deformation parameters in solids

Abstract

The research resulted in design and development of an original soft- and hardware system  which digitizes the analog signal and provides multichannel data collection from strain gauge sensors on the base of a 32-bit microcontroller. This system allows to conduct mechanical tests of solids for tension (compression), and also to control conditions of an experiment (temperature, magnetic field, etc.). The designed complex also provides determining and studying of activating parameters of plastic flow in metals and alloys at tests for tension. The registration speed of deformation processes can reach about 10^-3 с^-1, and accuracy of measuring no less than 10 bits of useful signal.
