摘要
基于经典电磁场理论,研究了线圈感应器的磁场分布特性以及管件上涡电流的分布状态。建立了管件涡流区和空气区等非涡流区的场方程组,给出了边界条件。针对汇气管拔制特性,设计了加热感应器;利用ANSYS Workbench软件进行磁、热耦合仿真分析。通过与试验结果的对比验证了感应器设计的合理性。并针对线圈加热冷区以及改善加热的不均衡问题提出改进方法。
Based on the classical electromagnetic field theory,the magnetic field distribution characteristics of coil inductor and the distribution state of vortex current on tube were studied.The field equations of the eddy current region and the non-eddy current region of air were established,and the boundary conditions were given.A heating inductor was designed according to the pull-out characteristics of sink pipe.Magnetocalorimetric coupling simulation analysis was carried by using ANSYS Workbench software.The rationality of the sensor design was verified by comparing is with the experimental results.An improved method was proposed to improve the cooling zone of coil heating and the unequalization of heating.
