VA One把有限元分析（FEA），边界元分析（BEM），统计能量分析（SEA）及其混合分析集中于一个易于进行模拟的环境。同时，VA One提供有限元、边界元和统计能量分析一种严格的耦合形式，能够统一而可靠地进行全频谱范围的求解。从2004年以来，汽车，航空和铁路领域的一些世界性企业参与了ESI集团的结构噪声共同体（SBNC- Structure-borne Noise Consortium）项目，对发展和验证VA One方案做出了重要的贡献。联盟成员包括：空中客车德国部（Airbus Deutschland GmbH），波音商业飞机（Boeing Commercial Airplanes），庞巴迪运输（Bombardier Transportation），欧洲航空防务及航天公司研发中心（EADS CRC Research Centre GmbH），本田汽车（Honda Motor Co），三菱电机（Mitsubishi Motor Co），英国QinetiQ Ltd，立达汽车系统（Rieter Automotive Systems），大众汽车（Volkswagen AG）等。VA One包含有一系列的内部求解器，从而可以满足对振动噪声分析的需要。另外，这一工具软件还包括有与外部求解器的接口，以确保与目前振动噪声分析和设计过程的兼容性。VA One具有很大的灵活性，可以让用户选择基于成本、时间和计算资源的最佳模拟方案。这一软件还包含有强有力的管理工具，以快捷地根据CAD和FEA的数据建立模拟模型。VA One方案还提供了一个广泛的附加模块库，以确保软件可以集成于现有的CAE和设计过程中。例如，SYSWELD用于获得不同焊接连接具体的材料和几何属性。这个结果输入给VA One ，用于在一个耦合的有限元/SEA分析中定义局部连接细节。这种方法提供了一个评估复杂系统振动－声学响应考虑不同焊接和热处理过程影响的高效途径。
ESI Group, a leading innovator in virtual prototyping software and services for manufacturing industries, announces the new version of VA ONE 2021.1. This update contains several enhancements and corrections related to the modeling and simulation experience for its users across a wide range of industries, applications and methods.
Highlights of the version:
– Fixed potentially fatal error related to importing and converting closed cylinders from earlier versions
– Fixed potentially fatal error related to creating a flat flexible SEA subsystem from non-flat geometry
– Restored ability to copy and paste all nodes, including those created from sectioning operations
– Added the ability to copy and paste the navigation state of the 3D view
– Several plotting enhancements and fixes, including sorting and multiple curves
– When a solution fails to due to numerical issues related to junctions, VA ONE will print the name of the junction that caused the failure
– Improved the calculation of length and width for flexible doubly-curved SEA shells.
– Fixed bug where connected SEA subsystems created disconnected FE Subsystems after a meshing operation
– Several other bug fixes (including several related to the RAYON BEM Solver)
ESI VA One is a single environment for vibro-acoustics analysis and design. It allows engineers to perform accurate predictive noise and vibration design assessments early in the design cycle to meet product performance objectives. Users can meet aggressive design-time constraints, ensuring engineering decisions can be made when they most benefit the demands of a multi-disciplinary development environment.
The VA One environment is accessed from a standard user interface, covering the full frequency spectrum through a set of seamlessly coupled and proven modeling methods. With VA One, users achieve optimal design productivity without the need to deploy separate solutions requiring training for different user interfaces and data exchange between environments.
Massimo Martini, VA Engineer at IVECO S.p.a in Italy, explains the usefulness of VA One for vehicle performances especially for controlling noise and vibration inside the cabin.
Founded in 1973, ESI Group envisions a world where Industry commits to bold outcomes, addressing high stakes concerns – environmental impact, safety & comfort for consumers and workers, adaptable and sustainable business models. ESI provides reliable and customized solutions anchored on predictive physics modeling and virtual prototyping expertise to allow industries to make the right decisions at the right time, while managing their complexity. Acting principally in automotive & land transportation, aerospace, defense & naval, energy and heavy industry, ESI is present in more than 20 countries, employs 1200 people around the world and reported 2020 sales of €132.6 million. ESI is headquartered in France and is listed on compartment B of Euronext Paris.
