Eddy Current, Temperature Coupling Field Of Modeling And Finite Element Numerical Analysis

Nowadays, with the development of advanced technology, Finite Element Method presents greater advantage and strong development trend.With the engineering technology progresses and the characteristics of integration and synthesis, the Finite element method used in the analysis of single physical field couldn't match the demand of technology . The Coupled-Field Analysis with two or more physical field is strongly needed. So , the analysis of Coupled-Field in Finite Element Method has become the focus in correlative study. Now, the research of Coupled-Field Analysis is applied more and more in engineering physics .Firstly, based on the Isoparametric Finite Element Method, we constructed the mathematic analysis models with three-dimension (3D) eddy current, and 3D temperature fields. After that, automatic meshing technique in the former- managemet of the Finite Element Method was introduced.Secondly, we presented two analysis methods of Coupled-Field, and Sequential Coupled-Field Method and Direct Coupled-Field Method were introduced in detail.Furthermore, this thesis presented the coupled mathematic model of dynamic eddy current field and temperature field, and established the uniform EFM model of eddy current field and temperature field.For the Electromagnetic-Thermal Coupled field , by comparing and analysing the two coupled fields, we selected the sequential analysis method as the main method to construct the Electromagnetic-Thermal coupled mathematic and physical Finite element model.At last, we analysed and caculated the electromagnetic-thermal coupled fields of the heating steel ball in the induction heating equipment with the ANSYS software , and drawed some referential conclusions.
