Abstract:
Ansys EMC Plus is a platform-level electromagnetic modeling and simulation tool designed to deliver a comprehensive design-to-validation workflow for electromagnetic compatibility (EMC) and electromagnetic interference (EMI) issues. It specializes in analyzing electromagnetic effects on large platforms and cable EMI/EMC problems in various sectors, including aerospace, automotive, military, oil and gas, consumer electronics, and energy.
Simulating radiated emissions and susceptibility in electronics devices is an important effort of industrial importance. A key concern is the correlation between test lab measurements and their related simulations. Toward this end, EMA partnered with National Institute for Aviation Research (NIAR) in Wichita, Kansas to undertake a validation campaign to obtain validation data.
For these validations, EMA designed an electronic device including custom enclosures, printed circuit boards (PCBs), and cables as part of a non-proprietary electronic device. Further, EMA obtained common antennas.
The tests aimed to validate the radiated emissions from the custom electronic devices developed by EMA. Further, we analyzed the coupling between cable harnesses and antennas under various conditions using different types of antennas.
In each case, a simulation model of the test was developed in EMC Plus. The simulation results for emissions and coupling were compared to the test results in each case.
These results allow others to use EMC Plus predictions with confidence with the knowledge that they can correlate well in many cases with experimental measurements.
