SIMULATION FOR AUTOMOTIVE EMC
As automotive technology become increasingly complex, the electromagnetic environment both internal and external to the vehicle becomes more and more critical. With electric vehicles and autonomous vehicles progressing every model year, regulatory compliance and functional safety are some of the highest priorities. EMA has over forty years experience of creating complex simulations across a wide variety of platforms, from cars to aircraft to spacecraft. These simulations help platforms to meet all their requirements and perform flawlessly in a wide range of electromagnetic environmental conditions. EMA3D and MHARNESS can simulate the performance of items from the module level up to the full vehicle level, including the contributions of HV or LV cabling to both emissions and immunity issues. Our testing history and laboratory resources allow us to validate our models and results to ensure accuracy.
Given the immense cost and complexity of testing to regulations such as CISPR 12, 25, and soon 36, ISO 11451-1 and 2, ECE Reg 10.05, ICNIRP 1998/2010, not to mention the OEM-specific requirements, early simulation and modeling can give you peace of mind that when your DUT comes in for testing, either at the component or vehicle level, you’ll be able to pass the first time. This lets you save time and money and get to market in the most efficient way possible.

AUTOMOTIVE EMC MEASUREMENTS
EMA can perform developmental testing to assist with product design, pre-compliance, and troubleshooting. Our lab is able to conduct engineering evaluations of automotive components to a number of OEM specifications. We can also characterize cable transfer impedance and shielding effectiveness to allow for accurate design choices or problem mitigation. We can perform a number of transient tests including ESD to ensure design robustness or help with troubleshooting.
In addition, the EMA measurement services team can support all aspects of measurement to support antenna siting. This includes measuring RF systems for spurious emissions and responses; we can also perform antenna-to-antenna coupling measurements. Click here for more details.
