利用有限元及边界元法计算复杂磁性体磁场

THE APPLICATION OF LIMITEDELEMENT AND BOUNDARY ELEMENTMETHOD TO CALCULATE MAGNETICBODIE'S FIELD STRENGTH

近年来,利用有限元及边界元法对具有复杂边界条件的电磁场问题的计算有所发展,可使我们沿此途径对复杂磁性体的磁场特征的认识进一步深化,国内学者在这方面曾做过工作。在前人基础上,本文作了系统的推导和计算。下面先介绍有限元法的应用,再以此为基础,介绍结合边界元法求解磁性体磁场的计算。

By means of limited element and boundary element method, the values of field potential and strength inside and outside of magnetic bodies can be calculated exavtly even in complicated condition.It makes us being possible to understand the distribution of magnetic field of bodies more clearly.In this paper,formulas used for calculation are systematically developed and some examples are given.
