“VA One meets our needs for the vibro-acoustic analysis of spacecraft across the entire frequency range. With a single tool we can account for all the vibro-acoustic loads on our satellites.” Mr. José Luis Riobóo, Responsible for Engineering Organization at EADS CASA ESPACIO. |

“There are a large number of problems in the aerospace industry that are amenable to vibro-acoustics analysis. These include aircraft interior noise, specification of launch vehicle and satellite vibration environments, and detailed stress analysis of lightweight reflectors under high intensity acoustic loading, among others. Because of the wide range of frequencies involved, no one method can solve all of these problems. VA One is the only tool that includes solvers that can perform analysis and design studies for low-, mid-, and high frequency problems. This allows for fast and effective vibro-acoustic analysis and design of aerospace structures, significantly reducing cost and schedule impacts compared to build and test approaches” Dr. Paul Blelloch, Director, Aerospace Analysis, ATA Engineering Inc.
“One of the advantages of VA One for automotive applications is the ability to quickly start with the evaluation of simple yet useful conceptual models and progress through the evaluation of increasingly more sophisticated models as the design evolves. VA One can provide critical design assessments well before prototype vehicles are available such that proper noise control measures can be efficiently incorporated into the design; rather than inefficiently added as bandaids late in the program” LEAR CORPORATION
“Even with JM’s extensive testing capabilities, the next generation of acoustical solutions require sophisticated modeling techniques. ESI’s vibro-acoustics software compliments our experimental facility proving the ideal tool for a broad spectrum of projects ranging from building construction to aerospace acoustics” JOHNS MANSVILLE
“Boeing Integrated Defense has been a long term and successful AutoSEA2 user, and now has the capability of implementing all of the common vibro-acoustics analysis techniques, which are integrated into a single software package. The combined tools provide an efficient analysis environment when performing analysis to support Space Shuttle and International Space Station requirements. VA One is a standard software tool for Boeing Integrated Defense vibroacoustic analysis, and it is used to support a variety of other business activities” Ed O'Keefe, Associate Technical Fellow, BOEING INTEGRATED DEFENSE.
“Hybrid FE-SEA analysis 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 FE and SEA methods within one model allows the user to solve problems that cannot be addressed by applying SEA or FE methods separately" Ulf Orrenius, Senior Specialist : Acoustics and Vibration BOMBARDIER TRANSPORTATION
“VA One is intuitive and straightforward to use. I was able to complete a detailed, coupled Boundary Element analysis the first time that I used the code” Jeffrey Larko, Aerospace Engineer Structural Dynamics NASA GLENN RESEARCH CENTER
“The ability to simulate noise levels helped the engineers involved in the project consider the impact of their decisions on noise early in the design process, Engineers evaluated the impact of different types of absorptive materials and traded off their benefits against their costs. They quantified the impact of main paths and flanking paths so that they didn’t waste money reducing main paths in situations where the flanking paths would be controlling. The result was that noise on the Cascadia tractor was reduced by 5 to 6 dB below the previous generation and tests show that the Cascadia is one of the quietest cabs in North America.” Craig Birkett, Product Validation/Engineering Analysis FREIGHTLINER LLC
“By using ESI’s vibro-acoustic software we were able to obtain up to 15 dB reduction in the interior sound pressure levels in one of our vehicle platforms. The software is now used in production as part of our standard vehicle design process” Kazuki Fukui NISSAN MOTOR COMPANY
“Ensuring that our structures survive the harsh environments encountered during launch and liftoff is essential to our missions. Using VA One we can now predict the dynamic stress, strain and force in key components. This will help us to ensure that our structures are qualified for the acoustic and vibrational environments encountered during launch and liftoff”. Ben Tsoi, Senior Dynamics Environmental Engineer NASA JET PROPULSION LABORATORIES
