Abstract

The EMI/EMC risks are increasing in railway vehicles, and computer numerical simulation is an effective way for solving these problems, but there´re still some difficulties to be resolved in practical projects. This paper proposed a “Bottom-Up” simulation flow based on ANSYS electromagnetics CAE tools, to solve the EMI/EMC problems in railway vehicles form component level, equipment level to system level. Some practical simulation works were finished for a railway vehicle, including radiation of contact, EMI of cable harness, placement of high voltage components and vehicle body shielding.
