ESI Group Announces VA One 2007.5

By DE Editors

ESI Group (Paris, France), supplier of digital simulation software for prototyping and manufacturing processes released VA One 2007.5, a solution for simulating the response of vibro-acoustic systems across the full frequency range. This release introduces two new modules and includes more than 30 major enhancements to VA One, which seamlessly combines finite elements, boundary elements and statistical energy analysis (SEA) into one model.

The new VA One: Stress module is suited for determining the failure of structural components exposed to harsh vibro-acoustic environments. Applications include simulation of acoustic qualification testing for composite aerospace components and durability analysis for fixtures and connections.

The new VA One: Periodic Structure module is suited for modeling the vibro-acoustic response of large aerospace, marine, and rail structures across a broad frequency range. The module is the result of a two-year research program carried out by ESI Group in conjunction with NASA Langley, Virginia Tech, and Boeing Commercial Airplanes. The module is fully integrated within the VA One environment and is suited for modeling composite aircraft fuselage constructions, isogrid fairings, and extruded train floors.

VA One 2007.5 also contains more than 30 major enhancements such as new functionality for modeling perforated panels and perforated noise control treatments. This functionality expands the types of trim materials that can be modeled resulting in more accurate descriptions of sound package and interior noise in automotive, rail and aerospace applications.
