| 摘 要： | 等离子体破裂时随着等离子体电流的迅速衰减会在托卡马克装置真空室上产生很大的感应电流并导致电磁力。将EAST 装置真空室双层结构简化为若干环形线圈，采用互感矩阵法对破裂后真空室上感应电流及其导致的电磁力进行了模拟，用Fortran软件分析了真空室上感应电流、磁场、电磁力的变化规律。所得结果为未来托卡马克装置的工程设计改造提供理论依据。

| Abstract: | The sudden disappearance of plasma current during a disruption will produce large induced current and resulting in electromagnetic forces on the vacuum vessel of tokamak. In this paper, development of the induced current on EAST after a disruption vacuum vessel is studied. Using the mutual matrix method, by simplifying the double-shell structure to several dozens of circular coils, distribution of induced current and resulting in electromagnetic force is simulated, and the variations of the induced current, magnetic field and electromagnetic forces are analysed with Fortran software codes. Results obtained can provide a theoretical basis for the future engineering design for tokamak device. |
