A Simulation Study on NVH Performance of a Light-bus with the Combination of Rigid-elastic Coupling and Fluid-structure Interaction |

Abstract: | The modeling theory of rigid-elastic coupling and fluid-structure interaction are introduced and the corresponding vehicle models are set up based on a real light bus. Simulations are performed on the models, which demonstrates the application of the techniques of rigid-elastic coupling and fluid-structure interaction to the study on vehicle NVH performance. |
