Abstract
A self-powered magnetorheological (MR) seat suspension which includes a rotary MR damper and an electromagnetic induction (EMI) device was designed, constructed, and tested in this chapter. The inclusion of the self-powering component is able to activate this MR seat suspension without requiring external power supply, which contributes to reducing the cost. An MTS testing was performed to characterize the property of the self-powering MR seat suspension. Then its vibration reduction performance was evaluated under two kinds of vibration excitations. For this test, a robust control was used and the experimental results demonstrate that the ride comfort has achieved a higher level by using this controlled self-powering MR seat suspension.
