“…The tuned mass damper (TMD) is an effective way for the vibration control of structures and has been fully developed since Frahm [10] proposed the first tuned mass damper in his patent in 1911. Since then, many adaptive, semi-active and active methods for improving the performance of the TMD have been developed [11][12][13] and realized in practical engineering projects [14][15][16]. The dampers are adapted in conventional TMDs, and the energy absorbed by a TMD system is converted to heat and dissipated in the damper.…”

Abstract:A novel tuned heave plate energy-harvesting system (THPEH) is presented for the motion suppressing and energy harvesting of a semi-submersible platform. This THPEH system is designed based on the principle of a tuned mass damper (TMD) and is composed of spring supports, a power take-off system (PTO) and four movable heave plates. The permanent magnet linear generators (PMLG) are used as the PTO system in this design. A semi-submersible platform operating in the South China Sea is selected as the research subject for investigating the effects of the THPEH system on motion reduction and harvesting energy through numerical simulations. The numerical model of the platform and the THPEH system, which was established based on hydrodynamic analysis, is modified and validated by the results of the flume test of a 1:70 scale model. The effects of the parameters, including the size, the frequency ratio and the damping ratio of the THPEH system, are systematically investigated. The results show that this THPEH system, with proper parameters, could significantly reduce the motions of the semi-submersible platform and generate considerable power under different wave conditions.

Summary For the swing motion/vibration control of the suspended structural system, the tuned rotary inertia damper (TRID) has been proposed and investigated by the author previously. However it exhibits inherent robustness defect and limited applicability prospect due to its nature of being a passive tuning control system. In this paper, through the integration of active control philosophy with the rotary tuning control concept, an innovative control system named Active Rotary Inertia Driver (ARID) is proposed. First, based on the classical Lagrangian principle, the analytical model corresponding to the in‐plane swing vibration mode of the suspended structure subjected to point source excitations is established, where the structure is controlled by the ARID system. Second, the equations of motion are linearized for the purpose of engaging the classical linear control algorithm, for example, a linear quadratic regulator. The versatility of the proposed control strategy is analyzed. Furthermore, a shaking table experiment system is developed to validate the control effectiveness of the ARID system. The dynamic characteristics of the ARID system in terms of control capabilities, robustness, and stability are investigated through a series of designated shaking table tests. The performance of the ARID control system for swing vibration control of the suspended structure is successfully validated. The ARID system shows better robustness than the TRID system because it can apply control torque to the structure according to the structural response state feedback. The control algorithm and weight parameters can be designed according to need, which has been proven to be stable. The results of the paper establish a sound theoretical foundation for future investigations concerning the new control method and development.

“…Based on many practical applications and studies, the observation result shows that traditional vibration control devices such as the tuned mass damper (TMD) [4][5][6][7][8][9][10][11], tuned liquid damper (TLD) [12,13], particle damper (PD) [14], pounding tuned mass damper (PTMD) [15][16][17], and frictional tuned mass damper [18,19], are reliable and efficient for civil engineering structures. Active Mass Dampers (AMD) [20][21][22][23][24][25][26][27] have been widely studied in civil engineering for their superior effectiveness and larger spectral bandwidth [28][29][30][31][32]. There are many kinds of active [33][34][35][36] and semi-active [37] control devices for structural vibration control.…”

In traditional structural disaster prevention design, the effects of various disasters on structures are usually considered separately, and the effects of multi-type hazards are rarely considered. The traditional Tuned Mass Damper (TMD) and Active Mass Damper/Driver (AMD) are ineffective for the control of swing vibration. The Tuned Rotary Inertia Damper (TRID) system has the problems of being ineffective under multi-type hazard excitation and exhibiting a limited robustness. The Active Rotary Inertia Driver (ARID) system is proposed to solve these problems and the robustness of such an active control system is investigated in this paper. Firstly, the equations of motion corresponding to the in-plane swing vibration of the suspended structure with the ARID/TRID system are established. The control algorithm for the ARID system is designed based on the Linear Quadratic Regulator (LQR) algorithm. Next, numerical analyses carried out using Simulink are presented. Then, numerical analyses and experimental investigations corresponding to five working conditions, i.e., free vibration, forced vibration, sweep excitation, earthquake excitation, and sea wave excitation, are introduced. Lastly, the numerical analyses and experimental results of the ARID system, and numerical results of the TRID system, are compared to demonstrate the effectiveness and robustness of the ARID control system. It can be concluded that the ARID system is effective and feasible in structural swing vibration control and it exhibits a better control robustness than the TRID system. Furthermore, the feasibility of applying the ARID control system to multi-type hazard excitations is validated.
