Abstract :
The finite element model of a light bus body is established. The vibration modalities are evaluated using finite element software. The simulated results are compared with test date. It shows that the model has represented the vibration characteristics of the original structure. The finite element model for the acoustic cavity is established. The first step modality in the longitudinal direction of the acoustic cavity is evaluated. All of the modalities include body; frame and cavity acoustics are analyzed and discussed.
