In order to obtain an accurate structural dynamics model, this paper adopts a model update method that integrates the Kriging model and the MOGA algorithm for the GARTEUR aircraft to verify the feasibility of using a fusion of the Kriging model and the MOGA algorithm in the dynamics model correction. The initial parameters of the aircraft model were first screened using Spearman correlation analysis and the introduction of a significance level coefficient P. The screened parameters were then used as design variables to obtain the initial sample points using the OSF experimental design method, construct the Kriging response surface model, use the difference between the response surface calculation results and the experimental results as the objective function, and finally the MOGA algorithm is used to optimize the objective function, search for the Pareto optimal solution and add validation points to the candidate points to check its accuracy. The results show that the updated GARTEUR aircraft model has good frequency reproduction and prediction capability, and meets the engineering accuracy requirements, proving the effectiveness and reliability of using the fused Kriging model and MOGA algorithm in the dynamics model revision.
