リニアモーターカー(MAGLEV)周辺の磁束密度分布に関する研究

抄録

It is very important to study the electromagnetic field around a linear motor car (MAGLEV), not only for predicting performance characteristics, but also to protect passengers from the strong magnetic field. In this study, three-dimensional finite-element analyses were applied to solve the governing equations, and the results were compared with experimental data. It was shown that the computational results satisfactorily agreed with the experimental results. Using the Newton-Raphson method, nonlinear analyses were also applied to study the shielding effects of a steel plate. From these results, it can be said that the finite-element analysis is the most powerful method by which to design the electromagnetic field of a linear motor car.
