Abstract
Due to the electromagnetic compatibility of automotive electronic equipment, an automatic system based on 3- dimensional mechanical-arm was put forward and designed to detect electromagnetic field intensity. Visualization in scientific computing is a visual representation of space, geometric shapes, colors, textures, animations, etc., which transforms complex and vast amounts of data into organized structures. In this paper, 3D visualization of electromagnetic field in real automotive environment is studied to provide the visualization of electromagnetic field data and the recorded intensity of electromagnetic. It implements three display functions of electromagnetic field in the light of visualization technology: 3D display of electromagnetic field distribution could show the strength and the trend of electromagnetic field. Extreme value display could pick up the maximum and minimum values. Critical scope display could draw the distribution of all points which range the users set. The design application field of whole system is very wide, and provide a feasible and practical reference for electromagnetic compatibility problem of large electrical equipment.
