“…It is worth noting, as observed by Vigui and Kerschen [20], that the efficiency of the BSA tends to that of the TMD without reaching it. As previously observed [21], if a better attenuation around a particular mode can be obtained by a fine tuning of the characteristics of the BSA (linear resonance and damping), it deteriorates the other. For example, the best attenuation (up to 20 dB) for the second mode is observed for a BSA linear resonance f N % 48 Hz as shown in the right curve of Fig.…”

“…For the case of three branches (Figs. [10][11][12], performing linearized stability analysis on the slow dynamics with respect to slow time, reveals that the middle branch is unstable while the other two are stable. Equilibrium points of stable and unstable branches are in the form of node (stable) and saddle node, respectively.…”

“…However, in this study, both absorbers are constrained to have the same damping and the presence of detached resonance curve was not taken into account. In [13], a linear flexible beam with an embedded NES/linear absorber was investigated, but no proper design procedure was proposed, which makes difficult the comparison of both solutions.…”
