【摘要】：對(duì)高溫超導(dǎo)塊材在行波磁場(chǎng)中的電磁-熱特性研究是掌握超導(dǎo)塊材在直線電機(jī)中良好應(yīng)用的基礎(chǔ).本文提出一種快速計(jì)算的仿真方法,建立了超導(dǎo)塊材處于行波磁場(chǎng)中的有限元模型來計(jì)算超導(dǎo)塊材內(nèi)的電磁和溫度分布.這個(gè)模型考慮了超導(dǎo)塊材的非線性E-J本構(gòu)關(guān)系及利用磁場(chǎng)強(qiáng)度法來分析行波磁場(chǎng)的頻率和幅值對(duì)塊材內(nèi)電磁和溫度分布的影響,并對(duì)提出的新方法與傳統(tǒng)方法的計(jì)算結(jié)果和計(jì)算時(shí)間進(jìn)行了對(duì)比,發(fā)現(xiàn)兩種模型的計(jì)算結(jié)果相同但本文提出的新方法計(jì)算時(shí)間更短.
[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.
