Research On Visual Soft System Of Numerical Analysis In Electromagnetic Fields

With the development of energy industry, the application of electrical equipments, such as electric motors, large capacity transformers, high voltage switches etc, are more and more used in many industrial fields. Therefore, it is essential for electrical manufacturers to design their products more precise, to meet the requirements of electrical products with higher quality and higher performance in modern society.It is difficult to achieve the satisfactory results both of analysis and calculation by using traditional method because of the different shapes of the devices, structure complexion, material non-Linearity and the reason of electromagnetism coupling. With the rapid development both of computer and calculating techniques, Numerical Analysis become more emphatic, especially, researchers always focus on analog electromagnetic fields by using Finite Element Method in the design electric products and optimize the products. But using object oriented programming to study Finite Element is a new method to design and construct Finite Element. This article researched Finite Element theory by using the method of object oriented programming, designed visual software system of Numerical Analysis of Electromagnetic Fields with the science attitude, combining the method of Numerical Analysisof Electromagnetic Fields with software science.First, this text introduce fundamental concepts and conditions of development about Object Oriented Finite Element, and discussed the way which is essentiality and flexibility in the application of electrical Numerical Analysis analysis software, and also systemic studied the designing method of object oriented programming. Second, it designed system structure of Object Oriented Finite Element software, and studied the visual software is completed based on windows 98/2000/xp in accordance with the above mentioned theory basis. This software has its own unique features in efficiency and serviceability.Finally, the Finite Element Analysis of electromagnetic fields of large capacity transformer and mechanic-electric equipments were carried by using software designed in the article, achieving the satisfactory results, certifying correct and efficient of the method of Finite Element.
