摘要/Abstract

摘要： 将比例边界有限元法应用到电机磁场分析计算中，采用加权余量法推导无旋磁场的比例边界有限元方程及其离散格式，给出相邻子域公共边上内部节点磁位求解方法.以具有解析解的电机磁场问题为例进行计算和对比分析，验证离散格式的正确性和比例边界有限元法求解电机磁场的可行性，为该方法在电机磁场问题中的应用打下基础.

Abstract: Scaled boundary finite element method (SBFEM) is used to analysis and calculate electromagnetic field problems. SBFEM equation and discrete format of irrotational magnetic fields are derived with weighted residual method. Solving method of inside common node on public edge of adjacent sub-domain is shown. A typical example that has analytical solution of electromagnetic field is used for comparative analysis, which verifies discrete format correctness and feasibility of the method. Foundation for method applications in electromagnetic field calculation is made.

Key words: scaled boundary finite element method, motor, magnetic field problem, analysis and calculation
