Dynamic simulation analysis and experimental verification of a typical aircraft structure

Abstract Finite element software was adopted to conduct the vibration modal analysis and frequency analysis of a typical aircraft structure, and modal verification tests were conducted on the typical aircraft structure. Based on the indicator functions, the effectiveness of experimental results was evaluated and the pure modal results as evaluation criteria for simulation analysis results were selected. Among the eight results, the simulation analysis results of six modes are in good agreement with the experimental results, while the two modes of the simulation analysis results are consistent with the experimental results.
