Kriging-MOMSA Finite Element Model Updating Method and Application to Ground Flutter Simulation Test
摘要
Abstract
Ground flutter simulation test is a closed-loop aeroelastic coupling system that includes multiple sub-modules,in which the accuracy of inputs and outputs between modules significantly affects the final experimental results.To in-hance the efficiency and accuracy of the finite element model in reduced-order real-time reconstruction of unsteady aero-dynamic force,based on the results of the phase separation method,an improved finite model updating method is pro-posed,which combines the Kriging model and Multi-objective Mantis Search Algorithm(MOMSA).The refined struc-tural finite element model is used as the input for the aerodynamic reduced-order model.Taking into account the control complexity and flutter accuracy optimization,a layout scheme with 3 loading points and 3 vibration pick-up points is ob-tained.And the flutter characteristics of the original system before and after modification,as well as the system recon-structed in the time domain,are compared.The results show that the proposed correction and optimization scheme estab-lished has high accuracy and efficiency.The corrected input file can obtain an aerodynamic reduced-order model that meets the accuracy requirements and provides a certain reference engineering applications.关键词
