Vibrational analysis of point-coupled structures

Vibration Analysis of systems with beam components is performed. A previously developed method called Internal Loading Decomposition is applied to this particular configuration. A beam is used as the master structure to which are added one or more substructures. The method is assessed for several variations of this configuration using finite element analysis. Numerical examples demonstrate how the method can be advantageously applied to analyze periodical structures. Finally, a sensitivity study is performed to illustrate the effect of compliance uncertainties on the vibrational response.
