Mathematical modelling and dynamical analysis of a magnetorheological elastomer tuneable absorber
Mathematical modelling and dynamical analysis of a magnetorheological elastomer tuneable absorber
Magnetorheological elastomers (MREs) are a smart material whose mechanical properties can be adjusted through an external magnetic field. Because their field dependent properties can be selectively tuned, MREs are highly suitable for vibration control system. In this study, the dynamical properties of MREs are investigated experimentally in shear mode under different driving frequency and strain amplitude. The results show that both of the storage modulus and loss modulus decrease slightly with the strain amplitude; whereas the driving frequencies lead to increasing storage modulus and a maximum in loss modulus. Based on experimental results, a mathematical model is proposed to predict the frequency- and amplitude-dependent properties of MREs and a dynamical system with an adaptive tuned vibration absorber is build up to estimate the control efficiency of MRE absorber. Compared to conventional absorber, the performance of vibration control is improved obviously with MRE absorbers.

Abstract
Magnetorheological elastomers (MREs) are a smart material whose mechanical properties can be adjusted through an external magnetic field. Because their field dependent properties can be selectively tuned, MREs are highly suitable for vibration control system. In this study, the dynamical properties of MREs are investigated experimentally in shear mode under different driving frequency and strain amplitude. The results show that both of the storage modulus and loss modulus decrease slightly with the strain amplitude; whereas the driving frequencies lead to increasing storage modulus and a maximum in loss modulus. Based on experimental results, a mathematical model is proposed to predict the frequency- and amplitude-dependent properties of MREs and a dynamical system with an adaptive tuned vibration absorber is build up to estimate the control efficiency of MRE absorber. Compared to conventional absorber, the performance of vibration control is improved obviously with MRE absorbers.
