摘　　要：采用有限元方法计算了垂直位移事故中ITER包层系统及周围主要部件的电磁场力和力矩。通过ANSYS APDL动态模拟垂直位移事件过程中等离子体电流的形状和大小,并加载外界磁场,计算得到了包括包层在内的所有导体内部的感应电流分布。通过计算,得到了各个位置的包层模块的力和力矩,可用于评估该事故下包层系统的安全性。Electromagnetic force and torque of ITER shield blanket system and their surrounding major component under vertical displacement event（VDE） were calculated with finite element method.ANSYS APDL was used to simulate the shape and magnitude of plasmas current dynamically in the VDE course,and external magnetic field was imposed,then the induced current distribution inside the all conductor including the blanket was obtained from the calculation.The force and torque for every blanket module was obtained to assess the safety of blanket system under VDE.
