Vibration damping performance of magnetorheological elastomer based NR/SBR

Abstract


This paper mainly studied mechanical performance of magnetorheological elastomer (MRE) based natural rubber and styrene butadiene rubber (NR/SBR). The theoretical analysis showed that the vibration and noise of centrifuge could be decreased by 8-20dB with the MRE based NR/SBR. Meanwhile, the strength analysis showed that the strength of MRE based NR/SBR could meet the demands of actual working conditions. Finally, it found that MRE based NR/SBR played an effective role in the noise reduction and the whole noise could be decreased by 10dBA based on the experimental comparison of noise and vibration between the original running wheel of centrifuge and the MRE-transformed running wheel of centrifuge.
