脉冲磁体的电感计算

Inductance Calculation for Pulsed Magnets

与有限元法相比,解析算法具有建模简单、可移植性强、计算效率高等优点,所以磁体设计时一般采用解析法计算其电感值。本文将主要讨论绕线磁体和铜皮磁体等两种磁体的电感解析计算方法。一般磁体电感的解析计算法,存在较多重复计算,使计算时间长、计算效率低。本文提出了一种改进计算方法,它剔除了重复计算步骤,可使计算效率大大提高。本文还依据安培环路定律和能量守定律推导出了一种解析铜皮磁体电感的计算方法,将每层铜皮逻辑划分为多匝,按绕线磁体计算,再将所得电感值经过折算便可得铜皮磁体的真实电感值。

The analytic method is more powerful transplantable capability and much higher computation efficiency than the FEA method,this is why the analytic methods are usually used in pulsed magnets designing programs.This paper will discuss the analytic methods of calculating the inductance of both coil magnets and tape magnets.An improved analytic method for the inductance calculation of coil magnets presented in this paper can make the calculating speed much faster than that of the conventional method.This paper also presents a new analytical method for calculating the inductance of tape magnets.All the calculation results obtained by the analytic methods presented in this paper show a good agreement with the experimental results.
