Abstract :
This paper compared airbag deployment properties between two simulation approaches in LS-DYNA: the thermodynamic-based control volume (CV) method and the Arbitrary-Lagrange-Eulerian (ALE-based) method. The results from airbag static deployment test and head form impact test indicated that the ALE approach is more accurate than CV approach in simulating airbag initial deployment stage, and the simplified CV approach is inappropriate for analysis of occupant safety in the Out-of-Position (OOP) case.
