2016, Mechanical Systems and Signal ProcessingCitation Excerpt :The advantages of FRF based approaches over modal based approaches in joint parameter identification were discussed by Nobari [18]. Hong and Lee [19] proposed a hybrid method which employs the experimentally measured and numerically simulated FRFs and identifies the structural joint parameters. Hwang [20] identified the joint parameters by employing the FRFs of a structure with joint and the FRFs of a structure without joint.
FRF based joint dynamics modeling and identification
2013, Mechanical Systems and Signal ProcessingCitation Excerpt :The CMS method is therefore more applicable for the finite element (FE) environment but it may be difficult to use for the experimental data. As a result of these limitations, another methodology (i.e. response-based methods) is introduced, which directly deals with the frequency response properties of the structure and does not require the extraction of modal data [6]. The receptance coupling (RC) method, which is a response-based method, couples substructures using experimentally or analytically obtained frequency response functions (FRFs) [7].
Identification of dynamic stiffness matrices of elastomeric joints using direct and inverse methods
2013, Mechanical Systems and Signal ProcessingCitation Excerpt :Joints such as fasteners, welds, bearings, and elastomers present many challenges in modeling, and thus, the development of identification methods has drawn much attention [1–11].
Identifying joints from measured reflection coefficients in beam-like structures with application to a pipe support
2010, Mechanical Systems and Signal ProcessingCitation Excerpt :Some techniques arrive at a frequency domain description of the joint without making any a priori assumptions about the physical form of the joint [1,2]. Other techniques presuppose a parametric joint model (e.g. masses, springs and dampers) and tune the parameter values so as to best match experimental data [3–5]. In the case of FE models, modal or frequency response data are frequently used as they are often readily measurable [6].
