Three-dimensional Eddy Current Field Finite Element Analysis And Applications

The dissertation research two aspects as follows:1. Finite element analysis of three-dimensional eddy fieldanalysis of basic principle and basic step of the time-stepping method and the state space technique for the solution of transient eddy current problems. Time-stepping method is widely applied in solving transient eddy field. The dissertation will take T-φ-φmethod for example to show the basic principle and basic step of the time-stepping method. As for the state space technique , we can see the analytical method of linear-time-constant state equation in electrical network analyse as one kind of extendability in finite element analysis of transient eddy field.2.The application of the eddy current finite element method in design and simulating of the high power electromagnetic oven.The dissertation analysis how the material characteristic and structure affect the out-put power of the electromagnetic oven. And we also research the electromagnetic compatibility and electromagnetic leakage of the electromagnetic oven. We mainly accomplish seven aspect as follow:1) the characteristic of the rectangle magnet block electromagnetic oven2) the design and simulating of 10kW electromagnetic oven3) the simulating of bi- concentric ring wire board electromagnetic oven4) analysis of the electromagnetic oven with one aluminium sheet isolated5) influence of ring added in the electromagnetic oven6) the research of electromagnetic induction with metal conducting wire lied in the electromagnetic oven7) the design and simulating of the bi-elliptic wire board electromagnetic oven3. thermal analysis of 10kW electromagnetic ovenThis article primarily analysis the thermal analysis of 10kW electromagnetic oven...
