ESI Releases Latest Version of Vibro-Acoustic Simulation Solution

ESI Group announced the latest release of VA One, which is used to predict and resolve potential noise and vibration problems in the development process. The solution enables the simulation of noise and vibration across the full frequency range by seamlessly combining key vibro-acoustic modeling methods, including finite elements (FEM), boundary elements (BEM), and statistical energy analysis (SEA) in a single model.

According to the company, the solution allows engineers to get a precise idea of a product’s future vibro-acoustic performance by setting up interior or exterior acoustic models, coupled with a vibrating structure having various types of excitations.

The new version now takes into account Hybrid Area junctions between FE cavities and SEA panels, enabling engineers to improve the characterization of small cavities, as required to develop home appliances, cabins, or small vehicles, for example. The solution also enables engineers to couple BEM and FE cavities, which allows users to simulate the vibro-acoustic performances of complex HVAC ducts.

Transmission Loss (TL) can now be calculated and plotted for all sources and receivers, including BEM, Semi-Infinite Fluid and Diffuse Acoustic Field (DAF). This is useful to users who need to model acoustic transmission loss through walls and panels, the company says.
