Three-way nonlinear hybrid energy dissipation self-resetting damper

The invention relates to a three-way nonlinear hybrid energy dissipation self-resetting damper. The three-way nonlinear hybrid energy dissipation self-resetting damper comprises a damper cavity body,a particle swarm, a buffer material, viscous liquid, variable stiffness springs and a fixed structure. The damper cavity body is composed of an inner cuboidal cavity and an outer cuboidal cavity. Theinner portion of the inner cuboidal cavity is paved with a layer of particle swarm, and the buffer material is pasted on the inner wall of the inner cuboidal cavity. The outer wall of the inner cuboidal cavity and the inner wall of the outer cuboidal cavity are connected by the variable stiffness springs, and the viscous liquid is arranged between the inner cuboidal cavity and the outer cuboidal cavity in a filling mode. The four variable stiffness springs are uniformly arranged at the bottom of the outer cuboidal cavity and are connected with a basic structure. The bottom of the outer cuboidal cavity is connected with the fixed structure in the horizontal direction through the two variable stiffness springs which are arranged in an orthogonal mode. By reasonably setting the stiffness of the nonlinear variable stiffness springs made from shape memory alloys, the damper can provide different stiffness in the horizontal, orthogonal and vertical directions to tune the frequency of the structure under the action of wind/earthquakes, and the vibration energy of the structure is dissipated through viscous energy-dissipation, spring energy-dissipation, friction and collision of the particle swarm and the like.
