“…[45][46][47][48][49]). Within the possible passive technological solutions currently available or under investigation for the mitigation of multi-storey buildings, tuned-mass-dampers (TMD) are widely used in structural engineering to reduce translational displacements and accelerations due to wind and seismic loads in bridges [50][51][52][53] and buildings or assemblies [54][55][56][57][58]. Den Hartog [59] first derived analytical expressions to determine the optimal values of mass, frequency and damping ratios of the TMD as a function of the dynamic properties of the structure.…”

“…Passive control methods were commonly adopted in engineering practices due to its low cost and design simplicity. Tuned mass damper (TMD) is a passive device attached to the main structure for damping enhancement, and it has been demonstrated that it can control structural vibrations due to wind, earthquake, and human‐induced loadings . The foremost TMD device developed by Frahm in 1909 does not include the inherent damping and only works in a narrow frequency range around the resonant frequency .…”

Summary This paper proposes a new passive control device, pendulum‐pounding tuned mass damper (PPTMD), to mitigate the response of lightly damped structures under various excitations. The proposed PPTMD consists of a tuned pendulum mass and a pounding boundary next to the equilibrium position of the pendulum mass. Moreover, a layer of viscoelastic materials called high energy‐dissipation rubber is attached on the pounding boundary to dissipate the vibration energy through impacts. A simplified impact force model was developed for modeling the pounding behavior of the high energy‐dissipation rubber pounding layer, and parameters in the simplified model were identified from free pounding experiments. The validation of the numerical method to simulate the dynamic behavior of the PPTMD was provided. The effectiveness of the PPTMD to control a single degree‐of‐freedom structure was numerically and experimentally studied under free vibration and forced vibration. The effects of the frequency tuning ratio, the coefficient of restitution, the excitation force amplitude, and the mass ratio were studied, respectively. Finally, the control performance of the PPTMD was compared with the classic tuned mass damper under free vibration, forced vibration, and several earthquake records. It is shown that the PPTMD can significantly increase the damping ratio of the controlled structure and effectively reduce the response of the controlled structure around the resonant frequency range. Furthermore, the PPTMD still achieves considerable control performance even if the frequency of the controlled structure varied in a wide range. Due to the different vibration control mechanism, the PPTMD outperforms the classic resonant frequency range in controlling the structural displacement response.

“…For verifying that an ECTMD is an effective way to control a large-scale structure, a large scale ECTMD was designed and constructed to control a large beam structure [34]. Wen et al [35] installed an ECTMD system on a footbridge to control the human-induced vibration, resulting in the large-amplitude vibrations being suppressed. Bourquin et al [36] proposed two ECTMDs to control the first two modes of a bridge mock-up and found that the maximum achievable damping is obtained when a desirable viscous damping level is selected.…”

Undesirable vibrations occurring in undersea pipeline structures due to ocean currents may shorten the lifecycle of pipeline structures and even lead to their failure. Therefore, it is desirable to find a feasible and effective device to suppress the subsea vibration. Eddy current tuned mass damper (ECTMD), which employs the damping force generated by the relative movement of a non-magnetic conductive metal (such as copper or aluminum) through a magnetic field, is demonstrated to be an efficient way in structural vibration control. However, the feasibility and effectiveness of ECTMD in a seawater environment has not been reported on before. In this paper, an experiment is conducted to validate the feasibility of an eddy current damper in a seawater environment. A submerged pipeline is used as the controlled structure to experimentally study the effectiveness of ECTMD. The dynamic properties of the submerged pipeline are obtained from dynamic tests and the finite element method (FEM). The optimum design of TMD with a linear spring-damper element for a damped primary structure is carried out through numerical optimization procedures and is used to determine the optimal frequency tuning ratio and damping ratio of ECTMD. In addition, the performance of ECTMD to control the submerged pipeline model is respectively studied in free vibration case and forced vibration case. The results show that the damping provided by eddy current in a seawater environment is only slightly varied compared to that in an air environment. With the optimal ECTMD control, vibration response of the submerged pipeline is significantly decreased.
