Insights on the Effects of Magnetic Forces on the Efficiency of Vibration Energy Harvesting Absorbers in Controlling Dynamical Systems

This study investigates the effects of magnetic constraints on a piezoelectric energy harvesting absorber while simultaneously controlling primary structure and harnessing energy. An accurate forcing representation force is investigated developed. A reduced-order model derived using Euler–Lagrange principle, impact evaluated absorber’s static position coupled natural frequency system. The results show that attractive magnet configurations cannot improve system substantially before pull-in occurs. rigorous eigenvalue problem analysis performed substrate thickness tip mass to effectively design an for multiple initial gap sizes repulsive configurations. Then, amplitude are studied characterized by determining effective simultaneous reduction in structure’s motion improvement harvester’s efficiency.
