Generally, it is difficult to employ inerters in the literature into applications which have restricted space. Furthermore, these devices usually require direct attachment to inertial ground. This contrasts with a classical tuned mass damper (TMD) device which can be deployed on a host structure without a grounded connection, making them a potentially more versatile solution for vibration absorption scenarios. This study proposes a new design of tuned inerter damper (TID) which utilizes a relatively small-scale frictionless mechanical inerter to improve the vibration suppression performance. The optimal parameters for the TID are obtained via a numerical optimisation method. The numerical simulation that is obtained with the optimal design parameters shows that the amplitude of the vibrations is suppressed. This result is also validated numerically. It is shown that the new design of TID can be successfully applied to applications that have limited space or where direct connection to an inertial ground is not possible.
