Investigation of acceptability of different mathematical and numerical models for description of liner acceleration and braking in magnetic compressor

The method of numerical simulation of flat liner movement is proposed. This method makes it possible to model the interaction between liner strip and solid support at kinematic characteristics corresponding to experimental characteristics. Three different models are considered to justify the choice of elasto-plastic model which is adequate for solution of problems of this sort. A number of calculations are carried out, the analysis of obtained results and the acceptability of each model is made. The numerical research of dependence of stress calculation accuracy from finite element type is performed.
