项目摘要
Softwares of various methods for 3-D eddy current analysis are developed, and problems of various methods are investigated. The flux and eddy current distributions of standard models for the verification of softwares are analyzed, and they are compared with measured values. The results obtained can be summarized as follows :1. Investigation of Problems of Various Methods of Analysis and Development of Softwares(1) The finite element formulations of various methods (A-phi, A-phi-OMEGA, T-OMEGA) and problems in applying each method are investigated.(2) The CPU time for edge element is shorter than that for nodal element.(3) The gauge condition of the A-phi method and the grad phi are investigated.(4) The boundary element method using the scalar potential and the accuracy of the combination method of finite and boundary elements are investigated. The surface magnetic charge method is expanded to eddy current analysis.(5) The representation of magnetization curve of anisotropic material in an arbitrary direction is investigated.(6) 3-D transient analysis of coupled problem including moving bodies is investigated.2. Analysis of Flux and Eddy Current Distributions of Verification Models and Comparison with Measured Values3-D magnetic field and eddy current distributions of verification models are analyzed, and the CPU time and memory storage are compared each other. The user friendly 3-D pre- and post-processors for finite element analysis are developed.The accurate measuring system of flux and eddy current distributions utilizing newly developed prove method is established. The measured 3-D flux and eddy current distributions are compared with calculated values.
