Acoustics: VA One
Lighter, faster and quieter
Government legislation, competitive pressure and tight development schedules mean you can’t afford to wait until your product is built to find unexpected noise and vibration problems. With ESI's vibro-acoustic software you no longer have to. Account for noise and vibration right at the design stage - no more costly delays or panic driven test-based solutions. You can diagnose potential noise and vibration problems up front in your development process. Manage risk by identifying possible problem areas that may need more detailed modeling or test based development, while you still have time to make an impact on the product!
The full spectrum of solutions ...
Whether you are creating SEA models of initial concept designs or fully detailed Finite Element and Boundary Element models of final prototypes, ESI has all the simulation methods you need. Design for noise and vibration performance across the full frequency spectrum, leveraging decades of company research.
With our unique way of coupling statistical and deterministic modeling methods in a hybrid way, you have the flexibility to make models as detailed or as simple as you need. Create system level noise and vibration models in a matter of hours and get solutions in seconds, even on a laptop. Our VA software helps you rank sources and identify dominant transmission paths quickly. Get answers to key design questions in real-time, not tomorrow or next week.
There is a large number of problems in the aerospace industry that is amenable to vibro-acoustic analysis. These include aircraft interior noise, specification of launch vehicle and satellite vibration environments, and detailed stress analysis of lightweight reflectors under high intensity acoustic loading, among others. Because of the wide range of frequencies involved, no one method can solve all of these problems. VA One is the only tool that includes solvers that can perform analysis and design studies for low-, mid-, and high-frequency problems. This allows for fast and effective vibro-acoustic analysis and design of aerospace structures, significantly reducing cost and schedule impacts compared to build and test approaches."
