Wave6| Aero-vibro-acoustics Simulation| Adaptive Corp


One of the new frontiers for product differentiation is noise and vibration. A wide variety of manufacturers want to analyze their products to reduce both measures in response to a variety of factors—whether they’re implementing new lightweight materials and constructions or responding to government environmental legislation or customer expectations. Competitive pressures are driving nearly every industry back to the analysis phase.

The next-generation vibro- and aero-vibro-acoustic simulation tool from Dassault Systèmes, Wave6, offers a wide variety of industry application simulations and unique analysis methods that efficiently and accurately simulate noise and vibration across the audible frequency range.

Wave6 is unique in its integration of all of these methods into a single common simulation engine, which means engineers can combine multiple methods in the same model. That way, the many complex sources acting on your system—including complex unsteady flow sources—can be characterized and analyzed. In addition, Wave6 diagnoses and ranks the multiple transmission paths of noise/vibration through the system, while also creating accurate models of the frequency-dependent dissipation and isolation that results from poroelastic noise control treatments and structural isolators.

Integrating Wave6 into a product design process means building noise and vibration performance into the product from day one—greatly reducing the risk of uncovering costly noise and vibration issues only once you’ve reached the physical prototype stage.

  • Aero-acoustics of a rigid structure’s exterior flow noise
  • Vibro-acoustics for airborne and structure-borne transmission paths
  • Aero-vibro-acoustics of interior wind noise resulting from fluctuating surface pressures
  • SEA (statistical energy analysis) methods to analyze components’ vibro-acoustic response at mid and high frequencies and wave propagation via arbitrary cross-sections
  • Structural finite elements in order to analyze low-frequency component vibration
  • Acoustic boundary elements in order to simulate acoustic wave propagation at low frequencies in bounded or unbounded acoustic spaces
  • Acoustic finite elements in order to describe the low-frequency response of bounded acoustic spaces
  • Linear and quadratic acoustic elements in order to account for acoustic property variations resulting from temperature and pressure variations calculated using CFD

  • CFD users: Existing CFD users will appreciate Wave6’s unique functionality for automatically pipelining and templating advanced noise and vibration analysis processes using high-level workflows—which means users don’t need to be specialists to predict noise and vibration performance. Wave6 also allows users to efficiently transfer geometry, meshes, and results to your noise and vibration model from your flow model without mandating data in the terabytes.
  • Vibro-acoustic analysis users: Leveraging modern software architecture, Wave6 delivers an integrated environment that improves vibro-acoustic model creation. Fully integrating automated model updates from upstream geometry changes, advanced volume extraction techniques, and geometry and meshing functionality means users focus on solving vibro-acoustic problems instead of managing software architecture. In addition, Wave6 offers next-generation noise and vibration analysis methods covering the whole audible frequency range.
  • FEA users: FEA software doesn’t always offer the advanced noise and vibration analysis functionality necessary for vibro-acoustics simulation—though existing structural FEA models are generally useful for problems in stress, dynamics, and statics. Wave6, however, can extend your existing FEA capabilities with state-of-the-art methods for noise and vibration analysis through the whole of the audible frequency range, whether you’re modeling acoustic radiation and transmission, random acoustic environments, or complex poroelastic materials.
  • Physical test users: While physical testing remains an important part of noise and vibration troubleshooting, Wave6 provides additional physical insights and helps improve your test processes. Given only a limited amount of time to test different physical product configurations and diagnose contributing sources and paths, it’s vital to ensure you’re testing the right things in the right amounts. With Wave6, you can create simple models that help you evaluate and analyze your test data, rank sources and paths, and grant confidence in your source levels.
