AIRBAG MODELING PROCESS WIZARD

Early layout and package studies to define:

• IP profile.
• Seat positions.
• Dummy positions.
• Deployed airbag positions.
• Interference checks.

H Point perturbations Sensors to track:

• Air bag volume.
• Proximity of dummy to surrounding vehicle envelope.
• Proximity of dummy to air bag.



MESHWORKS FOR CREATING

PARAMETRIC AIR BAG FE MODELS

• Using this, air-bag FEA models can be parameterized.
• CFD models pertaining to gas flow can be parameterized
• Air bag folding can be automated using the Morpher.

AIR BAG SHAPE OPTIMIZATION METHODOLOGY

Air bag FEA models parameterized using MeshWorks/Morpher are integrated with optimization tools such as Isight.
Using the process automation & optimization tools in Isight, the following studies are carried out:

• – DOE.
• – Design Exploration.
• – Optimization.
• – Robustness studies.
