Applications of Modal Analysis — Lesson 6

The application of modal analysis is the topic of this section, but before we get started, what better way to appreciate the application of modal analysis than with the calming sounds and vibrations of these Tibetan singing bowls. Striking and rubbing the bowls produce different sounds and excite different modes of the bowl.


So, now that we have covered all the fundamentals, let's tie them all together with some applications of modal analysis. We will reinforce the concepts through two applications; a tuning fork and a skyscraper. We will also illustrate how to think of a complex dynamic structure as something much simpler so we can easily use a simple formula to estimate the expected dynamic behavior. Are a tuning fork and a skyscraper all that different?

Let's get into this lesson and find out.
