Vibro-acoustic simulation tool supports virtual prototyping
The software supports the simulation of noise and vibration across the full frequency range by seamlessly combining key vibro-acoustic modeling methods: Finite Elements (FEM), Boundary Elements (BEM), and Statistical Energy Analysis (SEA) in a single model.
The latest version of VA One covers the full spectrum of frequencies with great flexibility, delivering precise vibro-acoustic simulation results. It allows engineers to get a precise idea of a product’s future vibro-acoustic performance by setting up interior or exterior acoustic models, coupled if necessary with a vibrating structure having various types of excitations. The latest version of VA One 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.
Using the tool, engineers can couple BEM and FE cavities to simulate a duct radiating noise externally; a situation relevant to investigating the noise from HVAC (heating, ventilation, and air conditioning) systems or automotive exhausts.
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, at any stage of the design or development project.
New functionalities that provide improved customer experience and workflow integration include GUI customization.
