Simulating the Electromagnetic Susceptibility of Automotive Vehicles in collaboration with RENAULT

The tremendous increase in the use of electronic devices in the automotive sector is leading to hard-to-manage EMC situations. The Joint Study presented in this paper is demonstrating the ability of Numerical EMC to be…

Shielding Effectiveness Calculations for Cabinets (1 – 30 GHz) in collaboration with HUAWEI

This paper deals with the computation of high-frequency fields which penetrate into two different cabinets with two different air-flow hole shapes. The software used for the simulations is Efield® and the two different…

Hybrid strategy to simulate millimeter-wave RADAR devices for automotive ADAS

A multiscale hybrid strategy is proposed to simulate Advanced Driver Assistance Systems (ADAS) in both Short Radar Range (SRR) and Long Radar Range (LRR). The first development stage was focusing on small sized radar…

Enhancements and validation of FPM fluid structure interaction module applied to curtain airbag deployment

Models to represent in position situations based upon uniform pressure assumptions are well established and have been used extensively in the automotive industry for more than 15 years. More recently, in the beginning…

Multiphysics modeling of high density IC encapsulation

A multi-physics modelling approach for simulating the plastic encapsulation of high density IC packages is presented. This modelling approach is used to predict the two-phase flow of a curing resin, the heat transfer in…

Windnoise : Coupling wind tunnel test data or cfd simulation to full vehicle vibro acoustic model

Wind noise has become in recent years a significant contributor to perceived sound inside automobiles. Many methods are nowadays available to couple wind tunnel or CFD (Computational Fluid Dynamics) data to a full…

Conjugate heat transfer in hypersonic flows

In certain applications, different regions of the computational domain experience flow conditions/physics that are so different that it is very difficult for a single solver to produce sufficiently accurate results…

Methodology to predict transient engine compartment air temperature following engine shut down

Cooling and heat protection of the engine compartment significantly impact the performance of combat vehicles. An increased heat load occurs during soak-back after engine shut down, where the fans are shut down. Heat is…

Analysis of influence of plastic bumper on radio wave characteristics

From the standpoint of vehicle appearance, vehicle radar units should be located behind plastic bumpers. Plastic bumpers are made of dielectric material, which causes reflection, scattering, refraction, and diffraction…

Estimation of the threat of IEMI to complex electronic systems

The threat of ultra wideband (UWB) sources is interesting for military issues. This paper summarizes information concerning the voltages generated from some commercially available UWB generator systems and their…
