METHOD FOR MEASURING COMPLEX MECHANICAL DEFORMATIONS BY MEANS OF AMORPHOUS METAL BAND AND DEVICE FOR CALIBRATION OF SENSITIVE ELEMENT

摘要

FIELD: measuring equipment.;SUBSTANCE: group of inventions relates to the field of deformation control measuring equipment. Technical result is achieved by using amorphous ribbon Fe80-xCoxP14B6 fixed on investigated object in pre-stressed state, and characteristics of magnetic hysteresis loop are registered at specified magnetizing field. Calculation of separate components of complex deformation is performed by calibration data for characteristics of magnetic hysteresis loop at different values. For calibration there used is device consisting of sensitive element in form of narrow amorphous tape, exciting and receiving coils, recording device and containing electromechanical system including two step motors for creation of two components of deformation – tension and torsion.;EFFECT: possibility to distinguish type and characteristics of deformation at their measurement.;2 cl, 7 dwg
