Through the study of two kinds of energy dissipation and shock absorbing devices, we noticed that the energy consumption mode of the friction type energy dissipation and shock absorbing device has great damage to the component itself, and the service life is not long, and the energy consumption of the friction type energy dissipation and shock absorbing device is similar to that of It is related to the displacement, and the frictional energy dissipation and shock absorbing device plays a very small role under the normal use load and small earthquake
However, hydraulic dampers cannot fully meet the needs of low-frequency and high-amplitude vibrations.

The invention discloses a compound self-resetting energy-dissipating and earthquake-reducing device and belongs to the technical field of energy dissipation and shock absorption. The device comprisesa sleeve, a friction damper, a slot and hydraulic dampers at two ends. The inner hydraulic damper and the outer hydraulic damper are separately located on the inner side and the outer side of the friction damper. Each hydraulic damper comprises a hydraulic cylinder, a piston rod, a piston, a damping liquid, a seal ring and a spring and the like. The friction damper comprises a friction plate and abolt. Under a normal use load and small earthquake action, only the outer hydraulic damper acts. At the moment, energy consumption of the device comprises hydraulic energy consumption and spring deformation energy consumption. When a middle earthquake or a major earthquake occurs, the inner and outer hydraulic dampers and the friction damper act simultaneously. By combining different energy-consuming modes, the compound self-resetting energy-dissipating and earthquake-reducing device not only meets the energy consumption demand under vibration of different intensity, but also improves the durability by designing make-up for each other's deficiencies.
Description
technical field [0001] The invention relates to a composite self-resetting energy dissipation and shock absorption device, which belongs to the technical field of energy dissipation and shock absorption. Background technique [0002] Energy-dissipating shock-absorbing devices play a significant role in reducing the damage caused by earthquakes and winds to building facilities. Among them, viscous energy-dissipating shock-absorbing devices have been widely used by changing the structural damping without changing the stiffness. The friction type energy dissipation shock absorber dissipates energy through friction as power consumption. Through the study of two kinds of energy dissipation and shock absorbing devices, we noticed that the energy consumption mode of the friction type energy dissipation and shock absorbing device has great damage to the component itself, and the service life is not long, and the energy consumption of the friction type energy dissipation and shock ab...
