Širokopásmová vibro-akustika pro jednodušší modelování a rychlejší simulace

3D softwarové akustické moduly systému Simcenter™ od společnosti Siemens Digital Industries Software obsahuje dvě klíčové inovativní technologie, metodu konečných prvků s adaptivním řazením (FEMAO) a automatické hledání hladin (AML), které zjednodušují modelování šíření vln a zrychlují vibro-akustické simulace. Díky těmto technologiím může odborník na akustické simulace nebo analytik metody konečných prvků (FE) snadno simulovat širokopásmové vibro-akustické problémy.

Innovative acoustic modeling technology

Finite element method with adaptive order (FEMAO) and automatically matched layer (AML) are acoustic modeling technologies that help eliminate the complexity of solving broadband vibro-acoustic problems. FEMAO uses a high-order FEM method in conjunction with a priori error indicator. AML is a flexible and efficient wave-absorbing method for free-field exterior acoustic applications. Both help eliminate the key mesh-based disadvantages of standard FEM.

Acoustic scattering of a submarine

Unsure about these innovative acoustic modeling technologies? The white paper goes through two examples to demonstrate their computational efficiency and accuracy. The first looks at the acoustic scattering of a submarine. The full details are outlined in the white paper.

Pass-by noise simulations

The second example using these acoustic modeling technologies involves an automotive pass-by noise simulation. Automotive pass-by noise is subject to a new regulation that will impact the vehicle development process, making technologies like FEMAO and AML important.
