Influence of Inerter in a 2 DOF Mechanical System

In this paper a 2-DOF Mechanical system using an inerter is analyzed. The inerter is a mechanical device that was proposed to passively attenuate vibrations. The prototype of the rack-pinion inerter with the two degrees of freedom system and simulation results obtained in the MSC Adams software are presented. Results of this analysis are presented, where it is observed that the inerter attenuates the vibration amplitudes, presenting a better performance in the second resonance, when it is coupled between the two masses, in addition to keeping the oscillations stable in both masses. These results are validated experimentally, under the conditions of the two system resonances.
