Analysis of the vertical isolation with inerter and clutching inerter damper considering the rocking effect

Clutching inerters enhanced tuned mass dampers for structural response mitigation under impulsive and seismic excitations

“…Control strategies with clutching inerters have shown better performance than their counterparts without clutches on SDOF 41 and MDOF structures, 43,44 rocking systems, 40,45 and vertical base isolation systems. 46 Clutching inerters not only retain the mass amplification effect of inerters but also reduce the sensitivity of the system to excitation frequency due to the large damping effect they provide. 47 However, most of the studies did not consider damping in the clutching inerters and assumed the clutching inerters automatically but unrealistically return to motionless state by the end of every oscillation.…”

“…To take advantage of this energy transmission in both moving directions, usually two clutching inerters that are oppositely directed are used (Figure 2). Control strategies with clutching inerters have shown better performance than their counterparts without clutches on SDOF 41 and MDOF structures, 43,44 rocking systems, 40,45 and vertical base isolation systems 46 . Clutching inerters not only retain the mass amplification effect of inerters but also reduce the sensitivity of the system to excitation frequency due to the large damping effect they provide 47 .…”
