Modeling Coupling Between Cables and Platforms for Electromagnetic Compatibility with Ansys EMA3D Cable

Automotive systems — and vertical takeoff and landing (VTOL) aircraft — have become complex electrical and RF devices. Fully electric powertrains and autonomous vehicle technologies increase the need for active electrical components, complex interconnected systems and the use of RF systems.

These systems are instrumental for vehicle control and must be analyzed at a higher safety standard. However, the large, fast-changing currents in electric drive systems can impact other electronics or RF systems on the platform, creating complex and challenging requirements. Both far- and near-field sensors require low-noise environments to ensure adequate performance. Real-time decision making for safety-critical situations requires high-speed communication and processing. Power quality from both on-board (powertrain) and off-board (utility grid) requires deliberate electromagnetic compatibility (EMC) analysis.

This webinar spotlights existing and emerging challenges facing electrification and cables and provides an overview of the requirements, test and analysis procedures used by EMC teams. It also describes how teams use simulation and analysis to optimize powertrain coupling. Additionally, it spotlights how validated analysis can guide cable routing and how separation rules enable maximum freedom for cable placement while ensuring compatibility.

  • Learn the steps to develop safety-compliant vehicle cable harnesses.
  • Understand the design challenges surrounding next-generation cars and VTOL systems.
  • Discover the requirements, test and analysis procedures used by EMC teams.
