Abstract

Indirect inverse substructuring dynamic analysis has been developed recently by the author of this paper and provides a new simple approach to determine the coupling dynamic stiffness, which is one of important characteristics estimating dynamic quality of a mechanical product assembly. Based on a physical model consisting of “8-mass plus 16-spring and 8-damping” elements, this paper provides a set of validation on the completeness and effectiveness of the approach. Experimental verification is also carried out by use of eighty testing data of frequency response functions (FRFs).
