This study presents a numerical analysis of an absorber/harvester system installed on semi-active suspension with the goal of mitigating vibration in the primary structure while simultaneously harvesting energy. The pendulum tuned mass absorber has been modified with a magnetic levitation harvester, and a semi-active suspension system consisting of MR damper and SMA spring is proposed for controlling dynamic response. Proper parameter configurations can effectively achieve energy harvesting along with vibration mitigation in the host system.
The paper presents numerical analysis of an absorber/harvester system installed on the semi-active suspension. The pendulum tuned mass absorber has been modified by use of a magnetic levitation harvester. The primary goal is to mitigate the vibration of the primary structure and the secondary goal is to harvest energy out of the vibration absorber simultaneously. This system is strongly nonlinear and the unstable regions are detected. Therefore, to control the dynamic response the semi-active suspension consisting of the magnetorheological (MR) damper and the shape memory alloy (SMA) spring is proposed. It is shown that with a proper configurations of parameters an effective energy harvesting can be obtained combined with vibration mitigation in the host system.
