Vibro-acoustics breakthrough

News

ESI Group has launched PAM-VA One, which is said to be the world's first fully integrated environment for simulating the response of vibro-acoustic systems across the entire frequency spectrum.

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.
