abstract

A systematic methodology is applied, leading to an accurate prediction of the dynamic response and the location of critical points in the superstructure of a real military vehicle. First the vehicle superstructure is modeled numerically with the finite element method. The model is then updated through an experimental modal analysis procedure in a support-free state. Mobility tests are performed next in real operating conditions, aimed at recording the acceleration time histories at the connection points of the superstructure with the chassis. These accelerations are used as ground excitation to the model. The stresses developed under the specific loading conditions are evaluated. The critical points of the superstructure are selected, based on the level of the larger stresses developed. Finally, strain gauges are placed at the critical points of the superstructure and a new set of measurements is carried out, in order to experimentally verify the stress levels developed. Comparison of the numerical and experimental data verifies that the method applied is quite reliable, indeed.
