In this paper , a novel dynamically synergistic regulation mechanism is proposed for rotation energy harvesting under the guidance of the dynamic regulation evolution, where nonlinear magnetic force and variable stiffness (centrifugal stiffening effect and penalty stiffness of adaptive-anastomotic barricades) synergistically regulate the dynamic behavior of the system.About:
