摘要
本文利用自制的NiCr-NiAl热电偶精确地测量了薄圆柱工件端面高频感应温度场的分布;应用有限元分析软件ANSYS/Thermal对高频感应加热过程的温度场进行了模拟。热电偶测量的数据直观可信,但测取工件温度场分布费时费力;有限元分析则可较为快速获知工件各处的温度,弥补了实验工作的不足。本文研究结果显示,两种方法得出的结果具有可比性,能够相互参照。
Thermal field of thin column for high frequency induction was exactly measured by homemade NiCr-NiAl thermocouple. It was simulated by finite element analysis （FEA） software, Analysis/Thermal. Although data got by high-performance thermocouple results show that data got by high-performance thermocouple is close to that through FEA.
