摘要

提出了一种用于精密电机力、转矩计算的三维自适应有限元分析算法。分析中采用边缘单元，引入节点力法分别进行力和力矩计算。采用对分法对局部误差较大的单元进行细化，利用相邻单元界面处的场连续条件对局部误差进行估计。通过二维和三维数值算例验证了该算法的有效性。

3D adaptive finite element method with edge elements [for machine calculations]

A 3D adaptive finite element analysis algorithm is developed for precise electric machine force and torque calculation. The edge elements are used in the analysis, and the nodal force method is introduced for force and torque calculation, respectively. The bisection method is adopted to refine the elements that have big local error, which is estimated using the field continuity condition at the interface between the adjacent elements. Through 2D and 3D numerical examples the validity of the developed algorithm is proved.
