Abstract

A semi-active torsional dynamic vibration absorber(DVA) with a magneto-rheological elastomer(MRE) as the core intelligent control element was developed. Based on the principle of DVA in torsional direction, the structure of the DVA was designed. The magnetic circuit simulation analysis of the absorber was carried out to ensure a strong closed magnetic field, which can effectively control the stiffness of MRE. The dynamics simulations of the DVA were carried out with the finite element software,which ensures that the natural frequency of the DVA can effectively follow the external excitation frequency to achieve the vibration absorption effect. The vibration absorber was installed on the corresponding position of the transmission system, and the simulation analysis of the system vibration response shows that the DVA can effectively reduce the transient fluctuation torque of the transmission system. The as-proposed MRE semi-active DVA provides a new idea for vibration reduction of rotating mechanical systems.
