摘　　要：为了研究局部热扰动下高温超导磁体热输运特性,建立了三维各向异性非稳态热传导模型,并采用有限体积法在时域与三维空间进行离散计算,获得了高温超导磁体瞬态温度响应。仿真结果表明:高温超导磁体由于自身热导与体积热容的存在,具有一定承受热冲击的能力,可根据各向异性高温超导磁体热输运特性提出改善磁体热性能的方法。To study the heat transmission characteristics of high-temperature superconducting（HTS）magnet under a local thermal disturbance,a three-dimensional transient orthotropic heat conduction model is established,which uses the finite volume method（FVM）for the discrete calculation in the time domain and three-dimensional space so as to bring a transient temperature response from HTS magnet.Simulation results show that HTS magnet has a certain capacity of bearing the thermal disturbance because of its thermal conductance and thermal capacity.The method of improving the thermal performance is proposed according to the orthotropic heat transfer characteristics of HTS magnet.
