中文摘要： 建立了包含运动参数和材料参数的涡流场和温度场的场路耦合数学模型。建立了神经网络预测模型，实现了神经网络对耦合场的预测，并将它与有限元求解相结合，提高了耦合场的计算速度。对横向磁通感应加热与行波感应加热进行了对比研究，分析了感应加热相关参数的影响。本项目分别提出了一种交错型行波感应加热器和一种楔型槽式行波感应加热器，较之传统结构，这两种感应加热器能获得更均的温度分布。行波感应加热除具有横向磁通感应加热的优点外，还能减小电磁力、振动和噪声，并能获得更加均匀的温度分布。在本项目研究的基础上，开发出我国首台行波感应加热设备，必然对我国金属制品的加工装备水平有重要的促进作用。

英文摘要： A coupled field-circuit mathematical model is presented to describe the coupled eddy current field and temperature field, considering the strip moving and material characteristics. In order to speed up the coupled field computation, a neural network prediction model is presented and used in combination with finite element solution. A comparison study between the TFIH and TWIH was presented and the parameters of the TWIH were analyzed. A Crossed-TWIH and a slot wedges TWIH are presented in this work. These new structures can get more uniform temperature distribution compared with traditional structure. Except those advantages exhibited in TFIHs, the TWIHs have other advantages like the reduction of the electromagnetic forces, vibration and noise, and can get more uniform temperature field distribution. Based on the research results, the TWIH device is expected to be developed firstly in our country, which will give important promotion for metallurgy engineering.
