Abstract [en]

A highly nonlinear model which consider the impact of the frequency, amplitude and magnetic field dependency for MS rubber and mobility for the foundation is developed for a MS rubber isolation system. Harmonic loadings ranging from 60 to 160 Hz with different levels of force magnitude are applied for the system. Vibration isolation effect is evaluated by assessing the energy flow into the foundation. It is found that the energy flow into the system and the vibration isolation effect for MS isolator are highly related to the amplitude and magnetic field dependency for MS rubber. Furthermore, by comparing the energy flow to the foundation under zero and saturation magnetic field, a control strategy to reduce the energy flow to the foundation by changing the magnetic field is obtained. After applying the control strategy it is found that the energy flow into the foundation can be reduced by about 20% by changing the magnetic field compared to traditional passive rubber isolators.
