ESI Group
has officially launched PAM-VA One at InterNoise 2005, the international trade fair for noise control engineering, in Rio de Janeiro, Brazil.
PAM-VA One is said to be the world's first fully integrated environment for simulating the response of vibro-acoustic systems across the entire frequency spectrum.
According to ESI Group, PAM VA One has been described by industry professionals as the most important breakthrough in vibro-acoustics in the past 20 years.
PAM-VA One incorporates Finite Element Analysis (FEA) and Statistical Energy Analysis (SEA) within one modelling environment. In addition, the software implements a method for creating and solving fully coupled FEA/SEA models.
This theoretical breakthrough extends the types of vibro-acoustic problems that can now be addressed with simulation. Since 2004, leading OEMs 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 is said to offer a comprehensive range of internal ‘solvers’ to meet analysis needs. The software also includes interfaces to external solvers so as 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 the creation of models from existing CAD and FEA data. PAM-VA One has an extensive library of add-on modules to ensure that the software can be easily integrated into existing CAE and design processes.
"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," commented Professor 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 simulation environment for full frequency vibro-acoustic analysis, will be available for its first customer shipment in October 2005.
