Aerospace and Automotive Electromagnetic Test Environments

Test Electromagnetic Compatibility (EMC) of Complex Aircraft and Automobiles Systems with a Full Electromagnetic (EM) Model.

EMA3D Cable

To assess vulnerability to lightning strikes, aviation engineers have to understand the specific lightning environment for the aircraft.

A manufacturer of civilian and military aircraft used Ansys EMA3D Cable to improve their understanding of aircraft system lightning response and validate a numerical approach to compliance that compared full aircraft simulations to full physical lightning transient analysis (LTA) tests.

Frequency-dependent Materials

Frequency dependent materials allow you to predict EMC performance for any frequency range using correct material properties.


Simulate System-Level Cable Electromagnetic Compatibility (EMC) and Real-World EMI Events

When you’re designing the wiring harness for the controls system of a helicopter or the power distribution system of a next generation electric vehicle (EV), unwanted electromagnetic system effects can drastically uphold long-term production and cost-effectiveness.

As systems increase in complexity, system-level simulation becomes increasingly crucial to properly design an EMC solution and mitigate design failure in the future. EMA3D boasts many capabilities that can help validate your design of a single cable assembly, the high-level system, and every system in between.



Key Features

Unwanted internal and external coupling can prevent or inhibit testing certifications. EMA3D Cable’s capabilities start with:

  • Shielding effectiveness analysis
  • High Intensity Radiated Fields (HIRF) and cable coupling
  • EMI crosstalk between cables
  • Current return network optimization
  • Cable signal integrity
  • Lightning and EMP coupling to equipment interfaces

Radiated emissions simulations can be performed in full platforms, allowing the users to compute electric and magnetic fields anywhere in space due to radiation from cables and components. The automated coupling to HFSS allows engineers to consider the radiation of high-fidelity components such as packages, PCBs and antennas.

The coupling from ideal sources or specific components to cables installed in realistic platforms can be easily computed in the simulation environment. Radiated immunity tests, such as High Intensity Radiated Fields (HIRF) or Electromagnetic Pulse (EMP), can be easily simulated in Ansys EMA3D Cable. 

Easily setup Bulk Current Injection (BCI) and conduct susceptibility tests on wiring harness bundles.

By using a very forgiving mesh, EMA3D Cable can handle extremely complex platforms to compute shielding effectiveness.

Compute induced voltage and currents on real wiring harness bundles using the transmission line solver.

Evaluate how the digital and analog signals are affected by the cable definition and external electromagnetic noise.
