Variable-stiffness variable-damping device
The invention provides a variable stiffness and variable damping device. The variable-rigidity and variable-damping device comprises a supporting frame, frame nodes, a variable-rigidity assembly and a variable-damping assembly. The supporting frame is fixed to a floor bottom plate. The frame joints comprise the upper joint fixed to a floor top plate, the left joint and the right joint which are installed on the supporting frame and can slide left and right, and the lower joint fixed to a floor bottom plate. The variable stiffness assembly comprises four groups of springs; two ends of each group of springs are respectively fixed on the upper node, the right node, the lower node and the left node in sequence to form a rhombus structure; the variable damping assembly comprises four sets of magnetorheological dampers, and the two ends of each set of magnetorheological damper are sequentially fixed to the upper node, the right node, the lower node and the left node respectively to form a rhombus structure. The rigidity of the variable-rigidity variable-damping device is adjusted through the included angle between the spring and the horizontal direction of the supporting frame. And the damping of the variable-stiffness variable-damping device is adjusted through the impressed current of the magnetorheological damper.
