Analisi vibroacustica ad ampio raggio per semplificare la modellazione e accelerare le simulazioni

Simulazioni acustiche con Simcenter 3D
I moduli acustici del software Simcenter™ 3D di Siemens Digital Industries Software includono due tecnologie innovative fondamentali ovvero il metodo degli elementi finiti con ordine adattativo (FEMAO, Finite Element Method with Adaptive Order) e la metodologia AML (Automatically Matched Layer), che semplificano la modellazione, risolvendo i problemi di propagazione delle onde e accelerando le simulazioni vibroacustiche. Grazie a queste tecnologie, uno specialista di simulazioni acustiche e un analista di elementi finiti (FE) sono in grado di simulare facilmente i fenomeni vibroacustici ad ampio raggio.

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.
