Abstract

We propose modeling the damping behavior of a structure containing embedded particle dampers using a friction-based model, where a lumped mass, representing the trapped particles, slides within the structure and dissipates its kinetic energy due to a frictional interface. The model was studied numerically and its dynamics were analyzed using a Hilbert-transfer-based identification method. To validate the model, beam-like structures were fabricated using additive manufacturing and their dynamic behavior was studied experimentally. The experiment results were analyzed using the same Hilbert-transfer-based methods. The Hilbert-transfer-based method was used to identify the parameters of an equivalent, general single-degree-of-freedom, nonlinear model. Using these tools, the instantaneous (amplitude-dependent) modal properties of the numerical model and experimental system were identified. The identification results showed that the model and the experimental system exhibit similar behavior, which corroborates the model.
