感应加热涡流场及工程设计问题的讨论

Study on the Eddy Current Field and Engineering Design of lnduction Heating

在分析感应加热机理的基础上，阐明了涡流场计算在感应加热工程设计中的重要意义。指出了目前工程中普遍采用的感应器电磁设计方法所存在的缺陷，以及数值计算方法分析涡流场的现状和所存在的问题，采用反演变换原理与数值方法相结合进行涡流场分析。

This paper shows the great significance of eddy current field calculation in engi-neering design of induction heating on the basis of studying the mechanism of induction heating.After pointing out the weakness of design theories for induction-heating coils which has won great popularity in engineering and summarizing the present situations of numerical approach for solving eddy current field problem,the paper presents a new way to compute the eddy current field by us-ing the inversion transform incorprated with the numerical method.
