MODERN ARCHITECTURE BOARD INFORMATION AND CONTROL SYSTEMS OF HEAVY VEHICLES

Abstract

Prospects for using the method for controlling the stress state of products made of highstrength steels based on recording signals of magnetic (MN) and magnetoacoustic (MAN) remagnetization noise are considered. The energy and emission characteristics of MN and MAN are determined by the restructuring of the magnetic texture of the ferromagnet by Brakhausen jumps, 180° and 90° domain walls, respectively, with its cyclic reversal of magnetization. Therefore, MN and MAN carry different information about the physical and mechanical properties of steels, and the parameters of their signals in interrelation can be used to construct new algorithms for monitoring and diagnosing the physical and mechanical properties of articles made of ferromagnetic materials, for example, the stressed state of the critical products from these steels. The main results on the development of the means of magneto-noise control, achieved at the department of electrical engineering and mechanics of Moscow Technological University (MGUPI), their applications in the technologies of engineering, aviation and oil and gas industries are presented.
