| Abstract: | A PSO-based satellite finite element model updating method is discussed in this paper. Firstly, the finite element modeling and the modal analysis are used. Secondly, the correlation analysis is carried out between the test results and the analysis results. Thirdly, the particle swarm optimization (PSO) algorithm is used to update the satellite''s finite element model, which improves the precision of the analysis and the prediction of the satellite, thus provides a new method for the system level model updating. |
| Keywords: | finite element modeling modal analysis correlation analysis particle swarm optimization algorithm model updating |
