The invention discloses a passive variable stiffness energy dissipation and shock absorption device. Comprising a bracket, a hydraulic cylinder, a rubber plug, a hole, oil, a piston, a rigidity element and a stepped shaft. A stepped shaft is fixedly connected into the hydraulic cylinder and penetrates through a damping hole in the piston. The piston is provided with a double-outlet rod piece in a matched mode. A bracket is arranged outside the hydraulic cylinder and fixedly connected with piston rods at the two ends. The bottom of the hydraulic cylinder is fixedly connected with a supported rigidity element. The stepped shaft is of a three-section type, rubber plugs are arranged at the steps respectively, and the holes can be plugged when the rubber plugs make contact with the holes. According to the invention, the purpose of improving the control effect is achieved by providing different additional rigidities under different displacement conditions of the structural member. The technical problems that a traditional active variable stiffness control system is unstable in control, large in energy consumption, limited in use condition and the like are solved. No external energy is needed, the output range is wide, feasibility is achieved in implementation, and the application and development prospects are very wide.
本发明公开了一种被动变刚度耗能减震装置。包括托架、液压缸、橡胶塞、孔隙、油液、活塞、刚度元件和阶梯轴。液压缸内固定连接阶梯轴，阶梯轴穿过活塞上的阻尼孔隙。活塞配套设有双出杆件；液压缸外设有托架，托架固定连接两端活塞杆；液压缸底部固定连接支撑的刚度元件。阶梯轴为三段式，在阶梯处分别设有橡胶塞，所述橡胶塞在接触所述孔隙时，能将孔隙堵住。本发明针对结构件在不同位移条件下，通过提供不同附加刚度以达到改善控制效果的目的。解决了传统主动变刚度控制系统所存在的控制不稳定，耗能大，使用条件具有局限性等技术问题。本发明不需要任何外部能源，出力范围广泛，实施起来具有可行性，应用发展的前景十分广阔。
