A case study in the Correlation of Analytical and Experimental Analysis
(-)
Abstract
For engineers designing products, direct comparisons oft~si-- ·
and analysis data have not been generally available. A means
of mathematically integrating, statistically correlating, and
comparing experimental modal analysis and finite element
modal analysis data is self-evident. To illustrate the need for
the approach to converging lest and finite clement methodology,
a case study of an automotive engine fan assembly has
been performed. The fan is a typical example of a component
design requiring consideration of dynamic characteristics.
The investigation progressed from a simplified lest and finite
element approach involving one blade in which there is ćry
lilllc correlation, lo a lest and finite clement model of the entire
assembly in which the correlation was very good. Until the
availability of commercial software, integration has required
e cxtcnsi,·c knowledge of computer operating systems and file structures and has been generally much easier said than done.
