【摘要】：对高温超导块材在行波磁场中的电磁-热特性研究是掌握超导块材在直线电机中良好应用的基础.本文提出一种快速计算的仿真方法,建立了超导块材处于行波磁场中的有限元模型来计算超导块材内的电磁和温度分布.这个模型考虑了超导块材的非线性E-J本构关系及利用磁场强度法来分析行波磁场的频率和幅值对块材内电磁和温度分布的影响,并对提出的新方法与传统方法的计算结果和计算时间进行了对比,发现两种模型的计算结果相同但本文提出的新方法计算时间更短.
[Abstract]:The study of electromagnetic and thermal characteristics of HTS bulk materials in traveling wave magnetic field is the basis for mastering the good application of HTS blocks in linear motors. A fast simulation method is proposed in this paper. The finite element model of superconducting bulk in traveling wave magnetic field is established to calculate the electromagnetic and temperature distribution in superconducting bulk. The nonlinear E-J constitutive relation of superconducting bulk is considered in this model and the traveling wave is analyzed by magnetic field intensity method. The influence of the frequency and amplitude of magnetic field on the electromagnetic and temperature distribution in the bulk, The results and time of the new method are compared with those of the traditional method. It is found that the results of the two models are the same but the calculation time of the new method proposed in this paper is much shorter.
