摘　　要：提出一种分析瞬态三维电磁场–电路–运动系统耦合问题的新方法,该方法考虑了外部电路、材料非线性、涡流影响以及运动等因素,适用于工程计算。对于三维瞬态涡流场与电路耦合问题,应用Crank-Nicholson法进行求解;对于运动问题,应用一种非协调网格技术的插值运动边界法进行求解;三维电磁转矩的计算应用节点力法实现。为验证该方法的有效性,将其应用于TeamWork问题10、24以及24的运动模型的分析与计算,得到的结果误差均小于2%且计算时间明显缩短,即该方法能较为高效准确地解决瞬态三维电磁场–电路–运动系统耦合的问题。A new method to solve the 3D transient electromagnetic field-circuit-torque coupling problem was proposed, in which the external circuits, nonlinear magnetic properties, eddy-current effects and movement were taken into account. The method can be applied to engineering. The transient 3D magnetic field circuit coupling problems were solved by the Crank-Nicholson method, and the problem of motion was handled by the interpolation movement interface method that was a kind of nonconforming movement technique The torque was calculated by nodal force method. To verify the validity of the method, it is applied to analyze the model of TEAM Problem 10, 24 and the moving model of problem 24. The errors are all less than 2% and the computation time is reduced evidently. That is, the new method can solve coupling problems of 3D transient electromagnetic field-circuit-moving system efficiently.
