| Abstract: | Taking omni-directional-type airbag landing device of "Mars Pathfinder" as an example, the folding airbag with the ruffle and the non-ruffer structure is modeled. Meanwhile, the equivalent models of the reinforcing ribs and shrinking ropes in the airbag are established. The inflating process of the airbag is simulated and analyzed by using the model with high computational efficiency and uniform pressure. The whole research work provides a good foundation for the parametric design of the omni-directional buffer airbag. |
