| Abstract: |
| Objective To solve the problem of long development cycle, high cost and unsatisfactory design effect of airbag. Methods In view of this problem, the cushioning process of airbag was modeled by analytical method. Through the non dimensional parameters, the analytical model was transformed into a non dimensional dynamical model. By means of the airbag parameter matching chart, the airbag cushion system was designed for matching based on test requirement. Then the model of airbag cushion system was established and analyzed by the Finite Element Method. Results The airbag cushion test system was built to carry out the drop test. The parameter matching method and simulation result were validated by the drop test. The error of maximum acceleration of counterweight platform and Maximum pressure of airbag were 1.6% and 3.1% respectively. Conclusion The accuracy of the finite element simulation can meet the analysis requirements, basically reflects the accrual airbag buffer characteristics. |
