Abstract

Model optimization has an important influence on the accuracy of simulation results based on finite element models. Existing research have been carried out various ideas for model correction to make the finite element model consistent with reality and easy for engineering practice. Good results have been achieved, but there are not too many researches based on the optimization of aircraft structure. In this paper, the finite element model of the wing rib beam structure is corrected by hammering modal experiment results, and on the basis of the optimized finite element model, the modal parameter identification is carried out for the wing rib beam structure by the NExT-ERA, and the results show that the identification results by the NExT-ERA are in good consistence with the finite element simulation results.
