MAGNETIC-ELASTIC PHENOMENA IN FERROMAGNETIC MATERIALS AT TORSION DEFORMATIONS

By Alexander Vasilievich Kadrov

Abstract

The investigation objects are ferromagnets - permendure 49KF2 and steel 51KhFA. The aim is to investigate the magnetic-elastic phenomena in the magnetostrictive materials at torsion deformations (effects of Widemann and Matteuchi) and to develop the principles of constructing the actuators and sensors operating on base of these phenomena. The shift magnetostrictive constants, sensitivities and magnetomechanical coupling rate for alloy 49KF2 have been determind. The construction principles and base designs of the sensors for mechanical action parameters and also the prototype of the low-frequency hydroacoustic radiator with small wave dimensions have been developed. The procedure has been proposed, and the equipment for vibration strolling of the oil pump rods has been developed. The full-scale tests of the prototypes of the sensors and actuators have been performedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
