Consortium aims to make modelling
guidelines
The MARI Consortium was officially launched with a meeting held in Paris in September 2006, and will continue until June 2008.
ESI Group has launched the European Marine, Aero, Rail, and Industrial structures (MARI) Consortium Participants of the MARI Consortium include industry leaders such as Alstom, BAE Systems, Bombardier Transportation, QinetiQ, Volvo Group and VTT
ESI Group's breakthrough VA One software sparked the interest of these companies to come together to brainstorm better guidelines and methods for modelling simulation.
VA One is the world's first and only fully integrated environment for vibro-acoustic simulation across the entire frequency spectrum.
Based on AutoSEA2, the industry standard software for mid and high-frequency noise and vibration design, and extended to encompass mid and-low frequency methods, VA One is the only simulation code on the market that contains a complete set of coupled vibro-acoustic analysis methods covering full frequency spectrum.
What makes VA One so unique is its ability to rigorously integrate the Finite Element Method (FEM), the Boundary Element Method (BEM), and the Statistical Energy Analysis (SEA) method within a single environment.
The underlying coupling theory contained in VA One allows the user to transparently deploy these different methodologies, making VA One a solution for structure-borne noise analysis.
This opens up brand new application domains to the vibro-acoustic simulation world.
It is now possible to build a single model with different modelling methods, couple them together and directly compute the vibro-acoustic response of a system.
The MARI Consortium was officially launched with a meeting held in Paris in September 2006, and will continue until June 2008.
The inaugural meeting provided a forum where each of the members shared details of target applications and objectives.
Several intermediate sessions will follow allowing participants to share knowledge and experience gained from executing the modelling tasks and report the progress made towards the mutually agreed objectives.
As a consortium member, each participant is provided with comprehensive training on an individual basis.
ESI Group supervises and supports the project to ensure that efforts are focused on the primary objectives of creating effective modelling guidelines and defining productivity enhancements that will facilitate cost and time-effective coupled Finite Element Analysis/Statistical Energy Analysis (FEEA) model creation for mid-frequency applications.
A previous Structure-Borne Noise Consortium, which looked at how to implement the unique technology breakthrough that rigorously couples FEM and SEA into an easy to use software, gave birth to VA One.
The consortium members evaluated for themselves the ease of use and the quality of the results by applying this new technology to their own industrial applications.
A follow-up consortium focusing on methodology has just been initiated.
The goals of the MARI Consortium are to define modelling guidelines and investigate aspects related to the automation of the model building process for the creation of coupled FEEA models within the VA One environment.
These objectives are set in the context of a technology transfer between ESI Group and the participants.
"The MARI Consortium is a great opportunity for each member to share experience in using VA One to model complex industrial structures for structure-borne noise prediction".
"The expertise gained from such activity and the interaction between members will help define commonly accepted modelling guidelines and provide ESI Group with valuable information to improve VA One's model-building capabilities and automation".
"The MARI Consortium is another example of ESI Group's commitment to provide vibro-acoustic industrial solutions across the full frequency range", says Denis Blanchet, ESI Group VA Product.
