With the rapid development of urban rail transit, floating slab vibration isolation system has become widely used in field due to its effective reduction and capabilities. Traditional vibration-isolation systems mainly focus on blocking transmission, neglecting energy harvesting. This paper proposes a magnetic-coupled double-wing negative stiffness harvester for slabs. A single-wing piezoelectric beam model finite element module are established. The modal output characteristics analyzed. Furthermore, force magnetically coupled results show that contribution width frequency gradually decreases with an increase length beam. thickness significantly influences characteristic frequency, load is exponentially related power. At optimal beam, decrease width. peak value magnetic gap. remanent strength indicates initial state ring more easily affected by external conditions. change axial becomes significant increased displacement. research enriches theoretical harvesting technology mechanism while providing important support subsequent experimental research, design, practical applications.
