Altair Partner Alliance Adds Porous Materials to NVH Offering

By DE Editors

The Altair Partner Alliance (APA) announced that the noise, vibration and harshness (NVH) analysis tool AlphaCell from MATELYS is now available for download by enabled HyperWorks users. According to the company, AlphaCell complements the APA’s current NVH offering by helping users simulate the vibro-acoustic response of multi-layer trims under various excitations.

“MATELYS is looking forward to the opportunity that this new partnership with Altair offers,” said Fran ois-Xavier Becot, co-manager at MATELYS. “AlphaCell expands the already comprehensive NVH library available through the Altair Partner Alliance to include simulation capabilities for porous materials, as well as many other materials, and analysis of vibro-acoustic excitation resulting from numerous sources. These new abilities will open doors for the two companies to work together in creating more complete NVH solutions for their joint customers.”
 
AlphaCell is a complete set of material acoustic models available,  including porous materials, perforated plates, double porosity materials and visco-elastic materials. It also encompasses stud modeling, the spatial windowing effect and a dedicated model for porous heterogeneous materials.

“We are delighted to bring AlphaCell’s sophisticated acoustic performance modeling capabilities to HyperWorks users,” said Jianmin Guan, senior program manager for noise, vibration and harshness at Altair. “With AlphaCell, users now have access to an extensive porous-material database that can be used to assess the acoustic absorption and transmission loss performance of any multi-layer acoustic trim design using various porous material models, including the BIOT model. AlphaCell’s solution expands Altair’s acoustic material modeling offerings and complements HyperWorks system-level structure and acoustic analysis solutions.”
