摘要：

在电磁感应加热中精确实现目标温度分布非常困难,鉴于此讨论实现目标温度分布的方法.建立合理的电磁物理模型：加热线圈和加热物体均等效为若干个螺线管；根据加热物体所需热量求出等效螺线管电流,并运用有限元法求取该物理模型中螺线管的等效电路参数,进而建立数学模型,用解析法估算出控制电压；建立磁热耦合场有限元分析模型,借助相关软件由电压和时间求出温度分布；为减小温度起伏引入冷却时间,建立一种数学与手动相结合的方法调整估算电压和冷却时间.检验表明,调整后的控制电压和冷却时间施加于系统所得的温度分布满足误差要求.估算过程简便地给出良好的电压初值,在此基础上调整程序精确求出理想的控制电压和冷却时间.
Abstract:

To realize certain temperature distribution precisely is difficult in electromagnetic induction heating, so a method of the controlling the aimed temperature distribution was introduced. Heating coils and heating object were equivalent as some solenoids respectively to build a reasonable physical model. A formula calculated the currents in heating object's equivalent solenoids according to the heat needed in heating object, and finite element method (FEM) got correlative parameters in equivalent solenoids so as to build a mathematical model, in which the voltages were derived in analytical method. Then the temperature field with certain voltages and time are computed by axial magneticthermal coupled FEM. Cooling time was introduced to make temperature undulate smoothly, a hybrid mathematical and manual method adjusted the voltages and cooling time to achieve ideal voltages and cooling time. The temperature distribution with obtained voltages and time met the error demand. The analytical method provides good initial voltages briefly, the adjusting procedure obtains required voltages and cooling time accurately.
