摘要
磁场有限元的数值解是节点矢量磁位,应将其转化为工程物理量.为了直观观察磁场分布情况,需要用图例定性地表示磁场的分布.使用面向对象的程序设计方法实现了磁场的矢量磁位等势线图和磁通量密度彩色云图,在云图中提出了光滑过渡处理方法,分布图反映的磁场性质与实际测得结果相一致.
Due to the reason that the numeric result of magnetic field FEM is a magnetic vector, it should be transformed to engineering physical parameters. To directly observe the distribution situation of magnetic field, it is necessary to qualitatively represent the distribution of magnetic field by distribution diagram. The magnetic vector contour and magnetic flux density cloud contour were implemented using object-oriented programming method. The smoothness method was proposed in cloud contour. The property of magnetic field, reflected by distribution diagram, accords well with the result of practical experiment.
