Error Effects on Identifying Coupling Dynamic Stiffness of a Mechanical Assembly by Indirect Inverse Substructuring Dynamic Analysis

Abstract:

Indirect inverse substructuring dynamic analysis has been developed recently by the author of this paper and provides a new simple approach to identify the coupling dynamic stiffness of mechanical assemblies. To analyze the error effects of measuring frequency response fuctions (FRFs) on the identification, this study implements a set of parametric studies on basis of a lamped mass model to deal with parametric studies which result in some guidance for applications of the approach.
