Based on this model, the influence of mass flow, compression displacement, and airbag thickness on flexible airbag ejection impact performance were studied. The results show that the ejection velocity of the flexible airbag increases as mass flow increases, but the excessive air mass flow does not improve the impact ejection performance of the airbag. The simulation results also demonstrate that the flexible airbag will oscillate reciprocally after it has no more contact with the moving rigid body and every node in the flexible airbag model has the same oscillating displacement. The analysis of compression displacement shows that it has a significant effect on the improvement of ejection performance. In conclusion, to improve the impact ejection performance of flexible airbag, the mass flow and compression displacement should be changed in a certain scope, which can provide reference for the topological structure design of the flexible airbag.
