Airbags are one of the major protection systems used in a car crash. They play one of the most important roles in preventing severe injuries and fatalities during vehicle crashes. The advancement of new technology and airbag regulations necessitates that airbags be tested for safety in all kinds of scenarios, including situations where the occupant interacts with the airbag before it is fully deployed.

Understanding the gas flow of the airbag is critical to understanding airbag performance. The Coupled Eulerian-Lagrangian Method in Abaqus/Explicit offers a sophisticated technique that can be used to simulate the dynamic gas flow in the airbag and realistically predict the shape of the airbag and pressure distribution during all stages of deployment.

Space flight re-entry vehicles need to withstand heavy impact upon landing and it is critical for engineers to understand the effects on the vehicle and the crew to ensure the safety of the mission.  In order to gain this insight, engineers need to be able to model both the space craft structure and the landing medium such as water, sand, clay, etc.

The coupled Eulerian-Lagrangian (CEL) method in Abaqus/Explicit provides the ability for capturing this interaction all within the framework of a single finite element model.  The simulation provides the means to investigate the peak accelerations faced by the crew or the payload during water landing.    

The sources of noise in a vehicle are many, including the engine, driveline, tire contact patch and road surface, brakes, and wind to name a few.  A Noise, Vibration, and Harshness (NVH) engineer is tasked with predicting these noises early in the design phase to make the necessary adjustments to ensure a harmonic ride, so to speak. The latest SIMULIA Tech Brief illustrates the effects that rolling tires have in contributing to NVH.
