Magnetorheological elastomer (MRE), as a field-dependent smart material, has been widely applied on base isolation for vibration reduction. However, the MRE isolation system often experiences large drift during a strong earthquake, which may cause mechanical failure. Additionally, its performance among the low-frequency range is still limited. To tackle these problems, this paper proposes a hybrid vibration isolation system which is composed of four stiffness softening MRE isolators and a passive ball-screw inerter. A simulation was developed to prove the effectiveness of the hybrid isolation ...

When you tap certain items your phone will vibrate just a bit, giving you a little feedback. Sometimes this is nice, but maybe you don’t like it. The good news is it’s easy to disable on any Android device.

This paper establishes a 7-degree-of-freedom full-vehicle suspension system with two 2-degree-of-freedom controllable electrically interconnected suspensions (EIS) to achieve the control effect of the entire vehicle. The motions between the sprung mass and unsprung masses are converted into electrical energy via the electromagnetic suspensions, and then the energy is electrically interconnected with the electrical network (EN). This research is based on the previous study of a 2-degree-of-freedom EIS system, which shows the vehicle performance at heave and roll is improved by controlling resis...
