Chicago, August 8, 2005
ESI Group, an innovative company committed to delivering state-of-the-art predictive vibro-acoustic solutions announced the official launch of PAM-VA One at InterNoise 2005, the International Congress and Exposition on Noise Control Engineering. PAM-VA One is the world's first fully integrated environment for simulating the response of vibro-acoustic systems across the entire frequency spectrum. This major product launch represents the latest ESI Group's innovative solution for vibro-acoustic simulation, analysis and design.
PAM-VA One incorporates Finite Element Analysis (FEA) and Statistical Energy Analysis (SEA) within a single easy to use modeling environment. In addition, the software implements a state-of-the-art method for creating and solving fully coupled FEA/SEA models. This major theoretical breakthrough significantly extends the types of vibro-acoustic problems that can now be addressed with simulation. Since 2004, leading OEM's in the automotive, aerospace, and rail industries have participated in ESI Group's "Structure-Borne Noise Consortium" and contributed to the development and validation of PAM-VA One.
PAM-VA One offers a comprehensive range of internal solvers to meet analysis needs. In addition, the software includes interfaces to external solvers to ensure compatibility with existing vibro-acoustic analysis and design processes. The flexibility of PAM-VA One lets the user choose the optimal simulation strategy based on cost, time and computational resources. The software also includes powerful model management tools for quick and easy creation of models from existing CAD and FEA data. PAM-VA One also has an extensive library of add-on modules to ensure that the software can be easily integrated into existing CAE and design processes.
"This software is the result of a long-term research and development effort by ESI Group and we are proud to announce its release. We have worked closely with our key customers and research partners to ensure that the software is validated and meets the needs of our worldwide user-base" says Dr. Phil Shorter, Lead Acoustic Scientist, ESI Group.
"The theory underpinning the FEA/SEA coupling part of PAM-VA One is the most important breakthrough in vibro-acoustics in the past 20 years." says Prof Ken Heron FREng, QinetiQ Senior Fellow. "This is a vital step towards predicting structure-borne noise at mid and high frequencies."
PAM-VA One, the One simulation environment for full frequency vibro-acoustic analysis will be available for first customer shipment in October 2005.
