Ansys Mechanical Acoustics

Acoustics is the study of sound. More specifically, it is the study of the generation, propagation, absorption, and reflection of sound pressure waves in an elastic medium.  Whether you are designing sonar, concert halls, speakers, mufflers, or any other type of acoustic device, this course will provide insight on how to use Ansys Mechanical™ structural finite element analysis software to perform Acoustics analysis.  It will provide a general understanding of acoustic phenomenon, terminology, and governing equations while introducing the procedures for performing modal, harmonic, and transient acoustics analysis in Ansys Mechanical software.

Learning Outcomes:

Following completion of this course, you will be able to:

• Understand the terminology and governing equations associated with acoustics.
• Identify the material properties needed to characterize an acoustic medium.
• Generate meshes suitable for modeling propagating sound waves.
• Account for sound wave propagation through both fluid and solid domains, effectively taking into consideration the fluid-structure interaction between the two domains.
• Perform modal acoustics analysis to compute modes of an acoustic cavity that may aid in identifying undesirable sources of sound.
• Identify and define various acoustic excitations and use them to perform harmonic acoustics analysis.
• Perform a fully coupled transient FSI solution with structural and acoustic domains.

Prerequisites:

• Good understanding of Ansys Mechanical Software.
