<<Eigenvalue analysis>>

Eigenvalue (resonant frequency):[Hz]

Mode[ 0] = 5.06139730e+002

Mode[ 1] = 7.76589632e+002

Mode[ 2] = 1.58726071e+003

Mode[ 3] = 1.92468740e+003

Mode[ 4] = 3.15995476e+003

Mode[ 5] = 4.14822255e+003

 

The resonant frequencies can be checked on Table.

 

The displacement diagram of Mode[0] is shown below. The contour diagram shows the displacement.

 

The displacement diagram of Mode[1] is shown below. The contour diagram below shows the displacement.

 

Mode[0] and Mode[1] exhibit completely different resonance.
