dc.description.abstract |
An advanced
finite-element
package,
tailored to the static and
dynamic
analysis of radial
impellers has been
produced. Two families
of new elements, one
for thin
and thick plates and
the other
for thin
and
thick shells,
have been derived
and proved
to perform very well
within a wide range of structural thicknesses. Static and
dynamic
economical solvers, two-
and three-dimensional
mesh generation and
plotting, sectorial symmetric analysis, steady state response,
transient response, and other programs are part of the large
number of
facilities
available in the
package.
The finite-element
package
has been
validated
by
solving a
large
number of simple case studies and comparing the package results
with those
obtained from
analytical solutions.
Two different
radial
impeller,
experimental validation
tests
have been
carried out, the first being the dynamic
analysis of a
radial impeller
using the time averaged
holographic technique, and the
second the
measurement of
the steady-state stresses
by
means of a
strain-gauge/slip ring assembly
for
a rotating
impeller. The
experimental results have been
shown to be in
good agreement with
those
obtained from the package. |
