Mesh Technique for the Finite Element Simulation of Acoustic Fluid-Solid Coupled Analysis

Article Preview

Abstract:

Noise and vibration analysis has become thoroughly researched in vehicle engineering where is needed to keep the noise level low and affect the vehicle users. The analysis in the paper shows a frequency response study where we will determine the frequency response on a coupled structure-fluid model. The study will be made on a simplified “train wagon“ model to show in a better way the differences between a perfect coupled structure-fluid model and a non-conformal coupling. The analysis shows that the distribution of the nodes for the two cases influences the results.
