摘要
本文应用全标量位有限元法,对带有多筒屏蔽的超导发电机的屏筒涡流和磁场进行了分析。此法的要点是将扩散方程和泊松方程的时变场边值问题简化为拉普拉斯方程恒稳场问题,因而使计算大为简化。理论计算结果与实验结果吻合较好。
A new finite element approach using a single sealer complex magneticpotential for the analysis of the eddy currents and the magnetic fields in theelectric machines and other electromagnetic devices is proposed,by which thetime-varying boundary value problem of the diffusion equation and the Poissonequation is simplified as a static problem of the Laplace equation.So thecalculation become easier,and the required computer memory and thecalculating time decrease.A computation example is presented which showsthat the accuracy of the present method is satisfactory.
