Key technologies of graphic processing of EMC software in vehicular communication system

论述了通信车系统EMC分析软件中图形处理的几项关键技术,包括几何模型验证的图形可视化、基于矩量法的散射体自动网格划分、散射体面电流彩色云图的生成、空间场强彩色云图的生成;给出了模型显示的染色算法、网格划分算法、面电流和场强彩色云图的生成算法.工程实践表明,这些方法实用、可靠,对其他分析软件中的图形处理有参考价值.

The key technologies of graphic processing for EMC software in the vehicular communication system were presented, including the graphic visualization for the validation of geometric models, the automatic mesh partition of scatterers based on the method of moment, the creation of the color map of surface current and electromagnetic field of the scatterers. Then, several algorithms were given for the colorization of displayed models , mesh partition, and the generation of color maps of surface current and electriomagnetic field. Experiments show that these methods are practical and reliable. They are also useful for graphic processing in other analysis software.
