Description of this data

A two-dimensional finite element (FE) model is presented, which can be used to validate methods and design criterions for vibroacoustics. A simple beam-like structure, providing different transmission paths for some structure-borne point excitation, is connected to a beam. The latter is acting as a radiator. The acoustic fluid is modeled by means of acoustic elements, and two different boundary conditions are implemented. This results in one model providing free-field conditions (halfspace) and one with a reverberant setting.

The model, therefore, enables one to analyze a full acoustic chain of effects (transmission of vibration through the structure and radiation) in a sufficiently complex setting with moderate model size.

For an application and a more detailed description of the model see:
