SYSTEM EQUIVALENT REDUCTION EXPANSION PROCESS (SEREP)

摘要

A new technique, the System Equivalent Reduction Expansion Process (SEREP), is presented. Originally formulated as a global mapping technique used to estimate rotational degrees of freedom for experimental modal data, SEREP has been found to provide improved accuracy in applications such as cross orthogonality checks between analytical and experimental modal vectors, linear and nonlinear forced response studies, and analytical model improvement. The theory upon which SEREP is based, as well as applications showing the advantages of this new technique are presented.
