AB  - Railway-induced ground vibration remains an important showstopper, especially in urban areas where significant levels of vibration are felt by residents. This paper presents a theoretical study of mitigation measures based on the use of Dynamic Vibration Absorbers (DVAs). Such devices can be tuned to a specific excitation frequency in order to reduce the forced response by absorbing the corresponding vibration resonance. The presented work focuses on the specific case of the T2000 tram circulating in Brussels, where large magnitudes of vibration are recorded during the passing over localized rail joints and turnouts. In order to design the DVAs, a numerical model is established, based on a recently developed two-step approach, which includes a coupled multibody model for the vehicle and a finite element/lumped mass model for the track. The model is completed with a 3D finite element model of the soil to simulate the ground wave propagation generated from the dynamic interaction between the vehicle and the track and can be used to evaluate the vibration level in the surrounding area. Tuned DVAs are also modelled, taking into account the design of each element. Finally, several comparisons are performed to quantify their efficiency and determine whether they are more effective in the vehicle or on the track.
