DS SIMULIA Wave6 2019.10.4.0 x64 可以高效、準確地模擬整個可聽頻率範圍內的噪聲和振動
噪聲和振動分析在幾乎每個行業都變得越來越重要。由於政府環境法規、新的輕質材料和結構、可檢測性、疲勞、消費者期望和競爭壓力,減少噪音和振動的需求正在增加。

無論應用程序如何,都需要一種方法來描述作用於系統上的復雜源(包括復雜的非定常流源)。您還需要一種方法來診斷和排序通過系統的各種噪聲傳輸路徑。你還需要精確的模型來描述由多孔彈性噪聲控制處理和結構隔離器引起的頻率依賴性耗散和隔離。查看可以用Wave6模擬的各種工業應用程序。

Wave6提供了獨特的分析方法,可以高效、準確地模擬整個可聽頻率範圍內的噪聲和振動。這些方法集成到單個通用引擎中,並由單個許可證控制。這使您能夠在同一模型中組合方法,並以在其他軟件包中根本不可能的方式有效地分析噪聲和振動問題。通過將Wave6集成到設計過程中,您可以確保在設計階段將噪音和振動性能內置到產品中,從而降低在物理原型制作過程中發現昂貴噪音和振動問題的風險。

Noise and vibration analysis is becoming increasingly important in virtually every industry. The need to reduce noise and vibration is increasing due to government environmental legislation, new lightweight materials and constructions, detectability, fatigue, consumer expectations and competitive pressures.

Regardless of the application, you need a way to characterize the complex sources acting on your systems (including complex unsteady flow sources). You also need a way to diagnose and rank the various transmission paths of noise through the system. And you need accurate models of the frequency dependent dissipation and isolation that arises from poroelastic noise control treatments and structural isolators. Check out the variety of Industry Applications that can be simulated with Wave6.

Wave6 provides unique Analysis Methods for efficiently and accurately simulating noise and vibration across the entire audible frequency range. These methods are integrated into a single common engine and controlled by a single license. This enables you to combine methods in the same model and efficiently analyze noise and vibration problems in ways that are simply not possible in other software packages. By integrating Wave6 into your design process you can ensure noise and vibration performance is built into your product at the design stage, which reduces the risk of discovering expensive noise and vibration problems during the physical prototyping process.

Key Capabilities:
Aero-acoustics of exterior flow noise from a rigid structure
Vibro-acoustics via airborne and structure-borne transmission paths
Aero-vibro-acoustics of interior wind noise due to fluctuating surface pressures
Statistical Energy Analysis (SEA) methods for analyzing vibro-acoustic response of components at mid and high frequencies and wave propagation through arbitrary cross-sections
Structural finite elements for analyzing vibration of components at low frequencies
Acoustic Boundary Elements for simulating acoustic wave propagation in bounded or unbounded acoustic spaces at low frequencies
Acoustic finite elements for describing the response of bounded acoustic spaces at low frequencies
Linear and quadratic acoustic elements account for variations in acoustic properties due to temperature and pressure variations computed using CFD
