Output of Frequency Analysis
After running a frequency study successfully, you can view:
You can plot displacement components of resonant
mode shapes:
UX
= Displacement in the X-direction
UY
= Displacement in the Y-direction
UZ
= Displacement in the Z-direction
URES = Resultant displacement (does not use
the reference geometry)
Mode shapes illustrate the
profile of the mode only (i.e., the displacement of nodes relative to
each other). The displacement values are calculated based on various normalization
procedures. The software normalizes each mode shape such that
{fi}T
[M] {fi} is equal
to [I]. Where {fi} is the vector representing the ith mode shape, {fi}T is its transpose, [M]
is the mass matrix, and [I] is
the unit matrix.
You can plot the deformed shape of a particular
mode. The corresponding frequency of the mode shape is shown on the plot.
This is a shaded plot of the resultant displacement.
You can create reports for the study.
