Electromechanical wave systems for mineral extraction

Abstract

The problems of the development of mineral deposits related to the technologies of extraction, transportation and processing of viscous, gaseous and bulk materials, including in mixed fractions, are analysed. To solve the problem of efficient transport technologies, a combination of electromagnetic effects with a bionic approach based on the use of the principles of motion dynamics of dolphins, fish and amphibians with a wave-like swimming method is proposed. The purpose of the study is to develop a structural, object-oriented mathematical model of a channel-type wave electromechanical converter that provides transportation and processing of minerals in liquid, viscous, gaseous and mixed fractions. It is noted that in this case, the existing methods of development and calculation of traditional electric drives are not suitable since the electromagnetic core must have a different spatial arrangement and have a distributed structure, the configuration of which is individual. The construction of a structural bionic model of an electromechanical system is based on the use of a system of travelling wave equations with fixed ends and the principles of the genetic concept in electromechanics. By directional application of genetic and geometric operators to flat and cylindrical forms of electromagnetic field sources, populations of a flow channel and combined structures connected to the ends of a travelling wave are obtained. An object-oriented mathematical model, methodology and algorithm for calculating a multi-motor electromechanical converter integrated into the design of a transport wave system have been developed. The optimal ratios of copper and steel of the electromagnetic core, the geometric dimensions of the flow channel and the number of switched electromagnetic modules providing energetically efficient generation of a travelling wave in the channel are established. The study's theoretical significance lies in the fact that the results obtained can be used in the development of technologies and the design of devices for the transportation and processing of liquid, viscous, gaseous, bulk materials and mixed fractions in the mining industry and in other areas.
