VA One是法国ESI集团于2005年推出的全频段振动噪声分析的模拟环境,代表着ESI集团在振动噪声模拟、分析和设计方面的最新技术,被业界专家评为振动噪声工程近二十年来最重大的突破。
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 VA One is a product from ESI GROUP designed for design and analysis in the field of vibroacoustics The program allows you to take into account the optimal characteristics of noise and vibration at the design stage and guarantee the fulfillment of vibro-acoustic requirements without additional costs and weight.The innovative integration of finite element analysis (FEA) and statistical analysis (SEA) into the same model allows the user to solve problems as successfully as when separately applying the SEA and FEA methods
VA One includes, of course, AutoSEA2, a standard vibration analysis program for the mid and high frequencies, and Rayon, a solver that has already proven its effectiveness in vibration analysis for the low frequency region. In addition, VA One employs a proprietary technology that guarantees a clear interaction of the finite element method (FEM) with the boundary element method (BEM) and the statistical analysis method (SEA) within a single analysis. VA One is the only solution that covers the full spectrum of vibroacoustic analysis in a friendly environment
