Enhancing suspension vibration reduction by diagonal inerter

Abstract

The diagonal inerter is integrated into a suspension vibration reduction system (SVRS). The dynamic model of the SVRS with diagonal inerter and damping is established. The dynamic model is of strong geometric nonlinearity. The retaining non-linearity up to cubic terms is validated under impact excitation. The conditions omitting the static deformation are determined. The effects of the diagonal inerter on the vibration reduction performance of the SVRS are explored under impact and random excitations. The vibration reduction performance of the proposed SVRS with both diagonal inerter and damping is better than that of either the SVRS without them or the SVRS with the diagonal damping only.
