Abstract:

© 2019 Elsevier Ltd Vibration absorbers have the capacity to significantly reduce local and global system vibrations under both resonant and forced vibration conditions. The subset absorbers known as semi-active vibration absorbers are characterized by the ability to reduce vibrations across a range of resonance and forced vibration conditions. Achieving an optimal tuning scheme for these vibration absorbers under a variable frequency external excitation is critical for realising maximum performance of the system. In this paper according to the dynamic tuned vibration absorption principle, an innovative magnetorheological elastomer torsional vibration absorber is proposed and installed in the torsional vibration system. Through the proposed absorber tuning process, the change in each order of natural vibration of the torsional vibration system is thoroughly analysed. The analysis results are used to optimize the frequency tuning scheme and modify the structural design scheme of the torsional vibration absorber. The effectiveness and reliability of the improved frequency tuning scheme and the structural design scheme are verified by simulation results.
