摘　　要：对磁热双向耦合内置式电磁感应加热辊进行设计与仿真分析,根据麦克斯韦方程和温度微分方程,分别建立电磁场和温度场数学模型,通过磁热双向耦合方式进行求解。利用有限元仿真软件设计正交试验,研究线圈与辊内壁间距、电流大小、电流频率、线圈匝数对升温时间和温度均匀性的影响,并通过反向传播神经网络得到最佳参数组合。结果显示,线圈与辊内壁间距16mm、电流大小105A、电流频率11.7kHz、线圈匝数104为最佳参数组合,此时升温至平均温度250℃的时间为784s,温度均匀性为1.7527。The design and simulation analysis of the integrated electromagnetic induction heating roller with bidirectional magnetic-thermal coupling were carried out.Mathematical models for the electromagnetic field and temperature field were established based on Maxwell's equation and temperature differential equation.The model was solved by bidirectional magnetic-thermal coupling method.Orthogonal experiment was designed by using finite element simulation software to investigate the influence of coil-to-roll inner wall spacing,current magnitude,current frequency,and coil turns on heating time and temperature uniformity.The optimal parameter combination was determined through backpropagation neural network.The result shows that the optimal parameter combination is a coil-to-roll inner wall distance of 16 mm,a current magnitude of 105 A,a current frequency of 11.7 kHz,and 104 coil turns.Under this parameter combination,the time required to reach an average temperature of 250℃ is 784 seconds,and the temperature uniformity is 1.7527.
