Abstract:
In order to simulate automobiles curtain airbag deployment, the software LS-DYNA were used to build the curtain airbag model based on solid-liquid coupling ALE algorithm, the sets and coupling methods of main parameters were given. The simulation model was tested by the static initiation test and the drop weight test. The results show that the curtain airbag deploys in the location of charging port firstly, then the curtain airbag is inflated. The results of simalation and tests are in coincide. The peak value of simutation has 9% error compared to the peak value of drop weight acceleration. The study showes that the ALE model can effectively present the deploying of side-air-curtatin. 5 figs, 10 refs.
