Results from the modal analysis provide important
information to designers on the natural frequencies and their mode
shapes. Designers can modify the geometry to avoid a large
amplitude that may occur when the natural and forcing frequencies
are closed to each other. Since the ANSYS files of this problem
are available from the book website, readers are can explore the
solution behaviors by changing the problem geometry and
boundary conditions to increase understanding.
