摘　　要：为了获得磁感应成像(MIT)三维正问题的解,基于ANSYS软件建立三维磁感应成像测量系统模型,并采用有限元分析方法进行求解.为了验证有限元方法可靠性,建立了Griffiths系统模型,在这一模型基础上进行了相应仿真试验分析.结果与理论计算值及Griffiths的试验结果一致,证明所提方法适用于求解磁感应成像测量系统三维正问题,为进一步研究MIT反问题及更复杂测量系统的设计提供基础.The finite element analysis method was used to evaluate the forward problem of three- dimensional magnetic induction tomography （MIT）. The model of MIT measurement system was established by the ANSYS software. The Griffiths＇s system was simulated to validate the reliability of the finite element method. The corresponding tests of simulation analysis were performed based on this model. The results were corresponded with the theoretical value and the Griffiths＇ s test results. The results showed that the method was suitable for solving the forward problem of three-dimensional MIT measurement system, which provided the basis to the further study of MIT inverse problem and more complex measurement system design.
