ESI VA ONE 2019.0 全頻段振動噪聲分析的模擬環境 ESIVAONE2019.0VAOne是法國ESI集團於2005年推出的全頻段振動噪聲分析的模擬環境,代表著ESI集團在振動噪聲模擬、分析和設計方面的最新技術,被業界專家評為振動噪聲工程近二十年來最重大的突破。 VAOne把有限元分析(FEA),邊界元分析(BEM),統計能量分析(SEA)及其混合分析集中於一個易於進行模擬的環境。同時,VAOne提供有限元、邊界元和統計能量分析一種嚴格的耦合形式,能夠統一而可靠地進行全頻譜範圍的求解。 從2004年以來,汽車,航空和鐵路領域的一些世界性企業參與了ESI集團的結構噪聲共同體(SBNC-Structure-borneNoiseConsortium)項目,對發展和驗證VAOne方案做出了重要的貢獻。聯盟成員包括:空中客車德國部(AirbusDeutschlandGmbH),波音商業飛機(BoeingCommercialAirplanes),龐巴迪運輸(BombardierTransportation),歐洲航空防務及航天公司研發中心(EADSCRCResearchCentreGmbH),本田汽車(HondaMotorCo),三菱電機(MitsubishiMotorCo),英國QinetiQLtd,立達汽車系統(RieterAutomotiveSystems),大眾汽車(VolkswagenAG)等。 VAOne包含有一系列的內部求解器,從而可以滿足對振動噪聲分析的需要。另外,這一工具軟件還包括有與外部求解器的接口,以確保與目前振動噪聲分析和設計過程的兼容性。VAOne具有很大的靈活性,可以讓用戶選擇基於成本、時間和計算資源的最佳模擬方案。這一軟件還包含有強有力的管理工具,以快捷地根據CAD和FEA的數據建立模擬模型。VAOne方案還提供了一個廣泛的附加模塊庫,以確保軟件可以集成於現有的CAE和設計過程中。例如,SYSWELD用於獲得不同銲接連接具體的材料和幾何屬性。這個結果輸入給VAOne,用於在一個耦合的有限元/SEA分析中定義局部連接細節。這種方法提供了一個評估複雜系統振動-聲學響應考慮不同銲接和熱處理過程影響的高效途徑。 ESIVAONE2019.0|  ESIGroupispleasedtoannounceVAOne2019thatoffersarangeofenhancementsthatwillenableuserstoaddresscommonmodellingapplicationsintheautomotive,aerospace,marineandindustrysectorsevenmoreeasily.
