The experimental and predicted results show good agreement between the values of the natural frequency of the system at both off and on states. Transmissibility and natural frequency of the integrated system are obtained from properties of single device. Experimental results show significant shift in natural frequency, when activating the VSDIs. Dynamic testing on this integrated system has been performed to investigate the effectiveness of the VSDIs for vibration control. MREs' stiffness and damping properties can be altered by a magnetic field. The proposed VSDI consists of a traditional steel-rubber vibration absorber, as the passive element, and a magneto-rheological elastomer (MRE), with a controllable (or variable) stiffness and damping, as the semi-active element. The integrated system comprised of two VSDIs, a connecting plate and a mass. This study presents the feasibility of a new variable stiffness and damping isolator (VSDI) in an integrated vibratory system.
