The paper presents calibration and efficiency analyses for two different configurations of a resonant vibration absorber consisting of a spring, a damper and an inerter element. In the two configurations the damper is either in parallel with the spring or with the inerter element. A calibration procedure is described for the idealized single structural mass system, starting from the desired level of dynamic amplification, and leading to explicit formulae for the device parameters. The procedure is then extended to a flexible structure by accounting for flexibility and inertia effects from the non-resonant modes. The calibration procedure is given a unified format for the two absorber types, and the high efficiency – evaluated as the ability to reproduce the selected dynamic amplification level of the resonant mode – is demonstrated.
