摘要

本文的重点是用于大电流应用(如超导体应用)的电感元件的数值分析。分析的对象是铁磁磁芯的螺线管线圈。在等效电学参数(负载电流和电感)固定的情况下，对线圈进行几何数据分析。讨论了基于二维方法的数值模拟的一些方面。考虑了两种不同的模型——轴对称模型和平面模型。考虑了磁芯的非线性特性。比较了两种模型的计算结果，讨论了模型简化对计算结果的影响。该分析基于商业软件ANSYS，并使用ANSYS参数化设计语言(APDL)脚本进行。

Numerical comparison of coils devoted for high fields by 2D planar and axisymmetric FEM models

The paper is focused on numerical analysis of inductive elements used for high current applications (e.g. applications with superconductors). The subject of the analysis is solenoidal coil with ferromagnetic core. The coil is analyzed in respect of geometry data having its equivalent electrical parameters (load current and inductance) fixed. Some aspects of numerical modelling based on 2D approach is discussed. Two different models are taken into consideration - axisymmetric and planar one. Nonlinear properties of magnetic core are taken into account. Results calculated for both types of models are compared and the influence of model simplification on the results is discussed. The analysis is based on commercial software ANSYS and it is carried out using scripts of ANSYS Parametric Design Language (APDL).
