“…From a practical point of view, no “grounded” inerter has been installed in civil structures yet, whereas cases with the traditional TMD coupled with base isolation systems already exist 34,35 . Moreover, as far as the practical realization of the inerter is concerned, the current trend of literature suggests the use of ball screw inerters to avoid detrimental features such as backlash effects 36‐38 …”

“…The applications of inerter in various mechanical structures have been investigated, such as vehicle suspensions (Hu et al, 2014;Li et al, 2012;Nie et al, 2010;Ning et al, 2019;Smith and Wang, 2004;Wang and Chan, 2011;Yang et al, 2021), train suspension systems (Liao, 2006), building vibration control (Xu, 2005). A generator-based semi-active inerter was proposed to achieve energy harvesting and the captured energy was employed for vibration control of the system (Liu et al, 2020(Liu et al, , 2021Qian et al, 2019). A tunedinerter damper was applied to suppress the vibration of cables, and the results demonstrated that the system's response is improved when a tuned-inerter damper was used (Lazar et al, 2016;Radu et al, 2020).…”

To avoid the limitation of conventional vehicle magnetorheological (MR) suspension, a variable damping and inertia device is applied in the vehicle suspension with MR technology. A semi-active adaptive MR inerter (AMRI) is discussed. A quarter car suspension model with an AMRI installed in parallel with a double-ended MR damper (D-MRD) is considered. First, the vehicle suspension with variable damping and inertia is analyzed. The prototype of D-MRD and MR variable inertia flywheel (MRVIF) are fabricated and tested respectively. Then, the control model of D-MRD and MRVIF is developed on the basis of test data. An improved Fuzzy PID controller for the semi-active suspension with D-MRD and AMRI is formulated. Numerical simulation is investigated to validate the proposed variable damping and inertia device. The results demonstrate that the performance of the semi-active suspension with D-MRD and AMRI can achieve much better ride comfort than the semi-active suspension with only D-MRD or AMRI.

“…In Gonzalez‐Buelga et al, 29 it was verified that the H ∞ optimal solution of the tuning parameters of the TID on a SDOF system under force excitation is the same as TMD‐SDOF system, which is derived by the fixed‐point method. Sun et al 30,31 investigated the performance of serial and parallel TIDs in the base‐isolated building and derived the analytical solution of their tuning parameters via H 2 norm. Shen et al 4 presented the analytical closed‐form solutions of the TID‐SDOF system under base excitation through the fixed‐point method to reduce both structural displacement and acceleration.…”

Summary A novel dual‐functional inerter‐based damper, called electromagnetic tuned inerter damper (ETID), is presented in this paper for vibration control and energy harvesting. To evaluate the effectiveness of the ETID, the simplified model of ETID coupled with a single‐degree‐of‐freedom (SDOF) structure has been established. The H2 optimal design of the ETID‐SDOF system has been conducted, whose goal is to minimize the value of the root mean square (RMS) of the displacement and absolute acceleration of the primary structure. The analytical solutions of the dimensionless tuning parameters of the undamped ETID‐SDOF system have been derived. The control performance and robustness for the undamped SDOF system with ETID have been evaluated via numerical study compared with the undamped SDOF system with the tuned mass damper (TMD) system. The impact of the structural damping on the tuning parameters and performance indexes has also been investigated. Later, the performance of the optimal ETID‐SDOF system has been evaluated in the time domain via real earthquake excitations. The results show that the proposed optimal ETID‐SDOF system can sufficiently reduce the structural displacement or absolute acceleration and simultaneously harvest vibrational energy.
