Abstract

It needs FE(finite element) model updating of recovery airbag for improving simulation accuracy of cushion process. In this paper, the FE model was updated based on drop tests of payload-airbags system. Firstly, FE model of payload-airbags was established. Two parameters, include discharge coefficient of vent and friction coefficient between airbag and ground, were selected for updating by sensitivity analysis. The response surfaces of impact response vs the two parameters were established based on Design of experiments and FE model. Based on the response surfaces, the optimal solutions were solved by Genetic algorithm. It indicated that the FE model updating of airdrop airbag was efficient through comparison of test results and simulate results before and after updating.
