Abstract
The paper is aimed to model the electromagnetic acceleration and braking of the liner in magnetic compressor. The 2D approach corresponding to the longitudinal section of spatial region is considered. Liquid, elastic, and plastic models of the liner are presented. The comparative analysis of calculation results for different models and their correlation with experimental data are carried out. The research of the influence of circuit parameters on liner braking is done.
Highlights
Introduction and Statement of the ProblemThe unit “MOL” (“Magnetic Oblateness of Liners”) is aimed to study the operation of all stages of the “Baikal” unit module and the generation of electrical pulses of megajoule magnitude
The calculation results for elasto-plastic liner model with modified deformation curves are discussed in papers [8, 9, 12]
The process of the liner electrodynamic acceleration and braking in the magnetic compressor is presented in this paper
Summary
Introduction and Statement of the ProblemThe unit “MOL” (“Magnetic Oblateness of Liners”) is aimed to study the operation of all stages of the “Baikal” unit module and the generation of electrical pulses of megajoule magnitude. The model of a power sharpening cascade, i.e. the magnetic compressor (MC), have been developed for the “MOL”unit [1]. The operation of the cascade is based on the compression of a magnetic flow by a liner accelerated by electromagnetic forces till the velocity 1 km/sec. The liner is the aluminum belt which is strained by the tensioning device into a couple of parallel bands. The liner has the following typical sizes: the belt thickness (axial x length) is 2 mm, the belt width (axial y length) is about 21 cm, axial z belt length is about 80 cm, the distance between the parallel belts at the start time is about 20 cm.
