| 摘 要： | ITER超导托卡马克装置在运行之前要对磁体线圈及馈线系统进行冷却降温,以达到超导体工作所需的低温环境.文中利用大型有限元分析软件ANSYS的温度场分析模块,对纵场磁体馈线系统的降温过程进行模拟仿真,得到了不同时刻馈线上的温度分布情况.在得出冷却过程中馈线上的温度变化之后,又根据稳定状态时的温度分布对结构进行了热应力分析...

| Abstract: | The magnet coils and feeder system should be cooled down to achieve the low temperature environment desired by superconductor before the ITER superconducting Tokamak device running.The cooling-down process of the TF feeder was numerically simulated by using the thermal analysis module of ANSYS program of FEM,and the temperature distribution of feeder at different time was obtained.The temperature field in steady state was used to calculate the thermal stress and strain of the structure.Thus the cooling methods and structure design of feeder system were proved to be reasonable and the parameter criteria were provided for next work. |
