Résumé

L'objectif de l'utilisation de techniques de compréhension de haut niveau est d'améliorer le résultat global de tout processus. En tant que fournisseur de services complets de solutions ingénierie complexes aux problèmes de bruit dans l'environnement, il est nécessaire de disposer de connaissances spécialisées pour concevoir et fournir des solutions sur mesure compatibles avec diverses contraintes qui impliquent de nombreux sujets (acoustique, aérodynamique, structure, matériaux/compatibilité chimique). La physique associée à des produits apparemment simples, comme un silencieux acoustique industriel, est souvent complexe. Plus précisément, son étude devrait être décrite comme aéro-vibro-acoustique - où (1) l'écoulement de l'air provoque des vibrations dans la structure du silencieux, (2) les vibrations génèrent des bruits aériens et structurels, et (3) les composants du silencieux (c'est-à-dire les baffles) atténuent les bruits se propageant dans le conduit. Motivés par une meilleure compréhension des performances de nos produits, nous utilisons le logiciel Siemens pour circonvenir les essais exhaustifs en laboratoire dont le coût est prohibitif et qui sont, en général, limités à des géométries et des paramètres communs. Une approche systématique est nécessaire pour valider les corrélations entre les résultats simulés et les données empiriques. Pour ce faire, on commence par corréler les performances aérodynamiques des produits à l'aide de la dynamique des fluides numérique (CFD) afin de prévoir les valeurs de chute de pression et la répartition des forces sur la structure, puis on utilise des solveurs supplémentaires pour évaluer le stade vibro-acoustique de l'analyse.

Sogand Okhovatian is an undergraduate engineering student studying at University of Toronto. She's majoring in Mechanical engineering, specializing in Energy Systems and Manufacturing, and pursuing minors in Artificial Intelligence, Sustainable Energy, and Advanced Manufacturing. She is currently a research associate intern at Parklane Mechanical Acoustics. She possesses a variety of skills and knowledge from previous experience in the Energy industry (Hydro One, Peak Power), and material's science research, and her curiousity expands her skills and knowledge continuously.

Viken Koukounian, Parklane Mechanical Acoustics

Dr. Viken Koukounian (Ph.D., P.Eng.) is the Director of Engineering at Parklane Mechanical Acoustics, a manufacturing and licensed engineering company that provides end-to-end turnkey solutions for mechanical noise control and vibration isolation. He brings a deep understanding and passion for converging aero-vibro-acoustical theories and best practices, with more than a decade of experience from working in various sectors (HVAC, aerospace, rail, noise control, vibration isolation, ultrasonics and architectural acoustics) having worked at K.R. Moeller Associates Ltd. (manufacturer of LogiSon and Modio), Hatch Ltd. consulting engineers, Bombardier Aerospace, Bombardier Transportation, and Vibro-Acoustics (now a Swegon Group).

Viken is committed to, what he refers to, the 'Paradigm Shift'—where the needs and expectations (i.e., acoustical and speech privacy, acoustical comfort and communication) of the occupant dictate requirements for architectural spaces and the outdoor environment. He actively participates—as a registered Member or a nominated Subject Matter Expert—in various standardization committees, including the Acoustical Society of America (ASA), the American Society of Heating, Ventilation and Air-conditioning Engineers (ASHRAE), ASTM International, Green Building Initiative (GBI), International Organization of Standardization (ISO) on behalf of Standards Council of Canada (SCC), the U.S. Green Building Council (USGBC) and the International WELL Building Institute (IWBI).
