Operational Impact
The use of FEKO enabled Hyundai MOBIS to simulate the surface currents of the assembly consisting of equivalent source and AVM housing at several frequencies from 0.4 GHz to 4 GHz. This analysis provided a better understanding of the hotspots on the enclosure. Areas around the slots and the central mounting holes had higher current densities. By adjusting the width of the slots and connectors, these hotspots were reduced or even eliminated. Furthermore, the company was able to analyze the effect of each material on the shielding effectiveness and select the material providing the desired shielding factor against frequency. This comprehensive approach has significantly improved the EMC analysis process from 2D to 3D, enhancing the overall efficiency and effectiveness of the process. | |
Quantitative Benefit
Hyundai MOBIS was able to save 33% of the simulation time by adopting a system level approach based on model decomposition and 3D analysis in FEKO. | |
The company was able to maintain the accuracy of the simulation despite the reduction in time. | |
The use of FEKO allowed Hyundai MOBIS to select the best composite material in terms of shielding effectiveness. | |
