workbench的声固耦合问题

koolala2010 · 发表于 2010-7-15 21:47:11

请问各位大大，ansys 12.1 workbench能做声固耦合么？如果可以该如何设置？分析不同频率声音下，结构的振动情况，能否给1-2个经典例子，万分感谢！

自己顶一下，没有高手尝试过么？

1. Introduction:
Acoustic analyses in ANSYS provides insight to the propagation of sound, and both
visual and aural postprocessing can aid in this objective. This memo hopes to cover
postprocessing methods for acoustic problems other than standard contour and XY plots.

1. Introduction:
For many years, ANSYS has 2D and 3D acoustic elements, including those used to model an “infinite” boundary. These elements can be used in modal, harmonic, and transient analyses, and fluid-structural interaction can also be accounted for in these simulations.
This memo hopes to review the following topics related to harmonic acoustic analyses: basic comparison of structural and acoustic elements, modeling complex impedance boundary conditions, and defining complex pressure loading. A set of input files, which analyze the case of a simple radiating sphere, is included with this memo

谢谢版主！！！我正在研究，看看如何在workbench里实现，刚用ANSYS不久，流固耦合已经完成了，但是不知道如何在 workbench里面定义 acoustic elements（FLUID29/30），以及displacement DOF 的实现。能教教我么？
