A research project has been initiated to improve crash test and analysis correlation. The work described is focussed on the test and simulation results for a fuselage section. Two drop tests of the section were conducted. The first test was designed to excite the linear structural response for comparison with finite element modal analysis results. The second test was designed to provide data for correlation with crash simulations. An MSC.Dytran model was developed to generate nonlinear transient dynamic results. Following minor modifications, the same model was executed in MSC.Nastran in order to generate modal analysis results. The results presented in this paper concentrate on evaluation of the correlation methodologies for crash test data and finite element simulation results.
