Abstract: Expansion of experimental measured mode shapes using the system equivalent reduction and expansion process (SEREP), or any expansion process that uses mode shapes for that matter, can be hampered due to lack of a well-correlated ...

Abstract: Expansion of real-time operating data from limited measurements to obtain full-field displacement data has been performed for structures in air. This approach has shown great success, and its main advantage is that the ...

Abstract: Model reduction has been performed for several decades to allow for correlation of an analytical model to experimental data at a reduced number of points; however, traditional approaches have limitations. Static stiffness ...

Abstract: The threedimensional pointtracking (3DPT) measurement approach is used in conjunction with finite element (FE) method and modal expansion technique to predict fullfield dynamic response on a rotating structure. A rotating ...
