Research in the impact of curtain airbag deployment on interior

Abstract

In this paper, Hypermesh and LS-DYNA were used for simulation modeling of complex curtain airbag based on particle method. A static detonation slider impact test was designed to verify the validity of the simulation model. The paper focused on the impact of curtain airbag deployment on the surrounding interior. The results showed that: curtain airbag simulation model based on particle method was reasonable and valid; during the curtain airbag deployment process, trim panels on the edge of B-pillar and C-pillar received more concentrated stress and strain; the opposite direction aircraft had a major impact on the curtain airbag, and deformation of the trim panels on edge of B-pillar and C-pillar was bigger without guide frame. The research results provide effective ways and reference for the design of curtain airbag and interior system. © Springer-Verlag 2013.
