Vibrational Modes of a Racquetball Racket

Synopsis
The acoustics laboratory at Kettering University uses a technique known as Experimental Modal Analysis (EMA) to extract vibrational mode shapes, resonance frequencies and damping rates for structures. These animations illustrate bending, torsional amd membrane modes in a racquetball racket. There are a number vibrational modes in which the entire racket vibrates as one solid object - strings and frame together. These modes are generally grouped into two types, flexural bending modes and torsional modes. There are also a large number of vibrational modes in which the frame is pretty much immobile and the strings vibrate in a manner similar to a circular membrane.
