ESI Group Releases VA One 2007 for Vibro-Acoustic Analysis and
Design
 ESI Group have announced the release of VA One 2007. VA One is the
next generation of ESI Group's vibro-acoustic analysis software and
provides a complete solution for simulating the response of
vibro-acoustic systems across the entire frequency range. The
software enables optimal noise and vibration performance to be
accounted for at the design stage, and ensures that noise and
vibration specifications can be met without adding extra cost and
weight.
“VA One is a real leap forward when it comes to acoustical
modeling technologies and is likely to set the standard for
industrial computational acoustics of large structures for the
future. The innovative integration of finite elements (FE) and
statistical energy analysis (SEA) methods within one model allows
the user to solve problems that cannot be addressed by applying SEA
or FE methods separately,” says Ulf Orrenius, seniors
specialist of acoustics and vibration at Bombardier Transportation.
VA One seamlessly integrates AutoSEA2, the industry-standard
software for mid- and high-frequency noise and vibration analysis,
and Rayon, a proven solver for low-frequency vibro-acoustic
analysis. In addition, VA One contains patented technology for
rigorously coupling the finite element method (FEM), the boundary
element method (BEM) and SEA in a single analysis. VA One is the
only simulation solution on the market that covers the complete
spectrum of vibro-acoustic analysis in one easy-to-use environment.
“This new release of VA One significantly enhances the
performance of our core solvers and expands the types of problems
that can be addressed with vibro-acoustic simulation. The new
functionalities will enable our users to create more realistic
models of noise and vibration performance and improve productivity
by reducing the time spent creating and solving models,” says
Phil Shorter, director of VA product operations at ESI Group.
The VA One 2007 release contains 35 major enhancements including
faster solution times for SEA and BEM models, support for the
Windows Vista and Linux operating systems, and new functionality
for creating fast and accurate models of grommets, leaks,
apertures, and grillages.
