ANALYSIS AND ESTIMATION OF FACTORS DETERMINING ACCURACY OF COMPUTER SIMULATION RESULTS OF SHIELDING HOUSING PROPERTIES OF ELECTRONIC DEVICES
Annotation
Subject of Study.The factors determining accuracy of computer simulation have been studied. Properties of the protective shielding housings of electrical and electronic devices have been analyzed under conditions of external high-intensity alternating electromagnetic field. The influence of this electromagnetic field has been studied, and the interrelationships between geometric, magnetic and electric parameters of the housings and their shielding properties have been shown. Authenticity estimation of the performed numerical analysis of the shielding properties is given. Method. Estimation and analysis of electromagnetic environment at the location of these devices at their development phase were carried out by computer finite element simulation method. And with this, qualitative and quantitative properties of shielding interaction with the housing were studied depending on the means of electromagnetic field definition, finite element mesh density, magnetic and electrical parameters of the housing material. Main Results. It is shown that there are at least three significant factors that directly effect on accuracy and authenticity of the finite element simulation results. These factors include: uniformity of specified unidirectional external electromagnetic field, density of the finite element mesh generation, authenticity of magnetic and electrical properties of magnetic materials used while making design of shielding housings. Practical Relevance.The results can be applicable in taking well-grounded decisions when designing the housings of electrical and electronic devices (like protective shielding housings for wide range of strength and frequency of the external high-intensity alternating electromagnetic field).
