De gros chars aussi discrets que des petites souris ? L’armée américaine utilise la simulation pour réduire le bruit à l’intérieur de ses véhicules terrestres
ESI VA One nous a non seulement orientés vers des solutions vibro-acoustiques optimales et efficaces, mais a également ouvert la voie à l’évaluation d’une méthodologie de contrôle actif du bruit.Greg KangasIngénieur et Chef de Projet / Great Lakes Sound & Vibration
Founded in 1996, Great Lakes Sound & Vibration (GLSV) opened their doors to solve acoustic, shock, and vibration problems. Today they are a multi-functional engineering company that features a strong background in defense, marine, automotive, off-highway and recreational vehicle markets. Their strength lies in their diversity and ability to solve challenging problems that require a broad range of knowledge and varied capability. When GLSV teamed up with the United States Army Tank Automotive Research, Development and Engineering Center (TARDEC), the goal was to develop Active Noise Cancellation (ANC) system for reducing intake and exhaust noise and high-performance fan noise for fans and blowers used in military ground vehicle and power generation applications.
Having used ESI VA One before, GLSV knew the simulation software would be the best tool for the job. GLSV used VA One to design, analyze, and validate the development of Active Noise Cancellation (ANC) systems for the cancellation of exhaust and fan noise in all phases of the development cycle. They are developing ANC systems for low frequency (up to 300 Hz) exhaust and intake systems, as well as mid-frequency (up to 1400 Hz) fan applications. In addition, GLSV used VA One to develop and validate active control schemes, integrate the ANC system into exhaust and fan duct systems, determine the sizing of speaker components, establish how much power was required to produce anti-noise, and create optimal placement and geometry of the integrated ANC system. GLSV will continue to utilize VA One to accurately size ANC system for new applications, cutting down in development time by eliminating iterations, which equals a reduction time of roughly 75% for GLSV applications
