Investigation on the use of various decoupling approaches

Abstract

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. Decoupling the component is necessary in order to accomplish any additional design improvements. Decoupling can be performed different ways. Several approaches are considered for the evaluation of component decoupling from the system. Impedance and Mobility techniques are compared to an alternate force decoupling approach. Several models are studied to better understand the strengths and weaknesses of each of the techniques often employed. Several cases are studied and shown in the paper. ©2010 Society for Experimental Mechanics Inc.
