Abstract—In this investigation the concept of the cable-based tuned mass damper (CB-TMD) is presented. This is an oscillator that presents geometric nonlinearities and has peculiar characteristics of elasticity and energy dissipation. Through numerical simulations and experimental procedures, it is evaluated as an attenuator of free vibrations and forced vibrations. It was found that this shock absorber does not have a good performance in reducing the settling time of free vibrations; however, it can reduce the amplitude of forced vibration in a range of frequencies.
