모델링 간소화 및 시뮬레이션 가속화를 위한 광대역 진동 음향

Simcenter 3D Acoustics
Siemens Digital Industries Software의 Simcenter™ 3D 소프트웨어 음향 모듈에는 모델링을 간소화하면서 진동 전달 문제를 해결하고 음향-진동 시뮬레이션을 가속화하는 FEMAO (finite element method with adaptive order)와 AML (automatically matched layer)이라는 두 가지 혁신적 기술이 포함돼 있습니다. 이 기술을 사용해 음향 시뮬레이션 전문가와 일반적인 유한 요소 (FE) 해석자는 광대역 진동-음향 문제를 쉽게 시뮬레이션 할 수 있습니다.

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.
