Frequently Asked Questions

What is the modal analysis method?

Modal analysis method involves the determination of natural/resonant frequencies and associated mode shapes (vibration modes) of a component or structure under free (unforced) vibration. The modal analysis method is utilized for the solution of the equations of motion.

What is modal analysis in vibration?

Modal analysis is widely used for solving vibration problems that identify the modal parameters, natural frequencies, damping, and mode shapes of the structure under testing. Simulation software, i.e., FEA, uses a mathematical model of the structure, while experimental modal analysis uses data which is measured from a physical structure.

What is modmodal analysis in FEA?

Modal analysis is one of the most basic types of FEA simulation. This type of analysis is a dynamic analysis which is used to determine the modes of vibration of a mechanical system.

What is modal acoustics analysis?

Perform modal acoustics analysis to compute modes of an acoustic cavity that may aid in identifying undesirable sources of sound. Identity and define various acoustic excitations and use them to perform harmonic acoustics analysis. Training materials for this course are available with a Ansys Learning Hub Subscription.
