| Substructuring methods allow for the development of system models from component information. Often times however, system response needs to be improved through the modification of one or more component representations. When these individual components are unknown, system decoupling approaches can be implemented to identify component characteristics.;System decoupling can be performed in several ways. Several approaches are considered for the evaluation of component decoupling from the system using frequency response functions. While several techniques currently exist, an alternate technique is presented in this work which decouples using the force required to constrain two components of a system. This technique is compared to the Mobility, Impedance, and Inverse Frequency Based Substructuring and several models are studied to better understand the strengths and weaknesses of each of the techniques. Several issues related to noise, truncation, and rotational DOF are addressed on analytical and experimental structures. |
