Chaplygin E. The Development of Cylindrical Induction System for Magnetic-pulse Attraction of Thin Metal Sheets

Research object: electrodynamic processes in one-serial cylindrical inductor systems and systems with additional auxiliary screens for an attraction of the set sites of a surface of thin-walled metal sheets forces of pulse fields. Research purpose: research electromagnetic processes in thin-walled metals of features and working out effective cylindrical inductor systems for a magnitno-pulse attraction of the set sites of a metal surface. Research methods and apparatus: Theoretical researches electrodynamic processes in inductor systems are executed by means a mathematical apparatus of the theory of an electromagnetic field and technical electrodynamics, namely integration of the differential equations of private derivatives. The decision of the put regional problems was carried out by analytical methods of mathematical physics with the subsequent computer processing of the received results. In tools for magnitno-pulse processing of thin-walled sheet metals electromagnetic processes experimental researches were spent at specially developed stand for modelling. Theoretical and practical results: Researches value results of for practice consists that on their basis the effective design inductor systems for an attraction thin metal surfaces is created the set sites. The system for a magnitno-pulse attraction of metal sheets is offered and patented inductor. Novelty: For the first time it is established that in the presence an electromagnetic field through the thin metal sheet penetration, the induced currents lag behind on a phase a current inductor approximately on pi/2 that causes occurrence of normal making forces mutual an attraction inductor and sheet; Theoretically and experimentally is proved a design inductor systems with the auxiliary screen which creates forces of pulling of the set site of thin-walled metal preparation at low frequencies of electromagnetic fields; it is established that the effect of pulling is defined normal making intensity of the magnetic field which share increases at frequency reduction; Offered a technique of measurement of the induced currents in sheet preparation without application of auxiliary reformative devices. Degree of introduction: the Kharkov national automobile and highway university. Sphere of the use: mechanical engineering, magnitno-pulse processing of metals.
