Abstract:
|
This paper will present applications of the Proper Transformations based on both cross
spectral matrix and covariance matrix branches to analysis and identification of multi-variate
random pressure fields. The random pressure fields are determined due to the physical
measurements on some typical rectangular models in the wind tunnel tests. The significant roles of
the first covariance mode associated with the first principal coordinates as well as of the first
spectral eigenvalue and associated spectral mode are clarified in reconstructing the random
pressure fields and identifying the hidden physical phenomena inside this pressure fields. |
