Self-adaptive damper and device based on damper

Abstract

The invention provides a self-adaptive damper and a device based on the damper. The self-adaptive damper comprises a device shell, a functional rod, a first elastic assembly, a second elastic assembly, a first damping adjusting assembly and a second damping adjusting assembly. The functional rod penetrates through a movement channel in the device shell, a first containing space and a second containing space are formed between the functional rod and the device shell, and the first damping adjusting assembly and the second damping adjusting assembly are installed in the first containing space and the second containing space respectively. The second elastic assembly is installed between the first damping adjusting assembly and the second damping adjusting assembly, the first elastic assemblycomprises a first elastic body and a second elastic body, and the first elastic body and the second elastic body are installed at the two ends of the device shell respectively. According to the damper, the damping-adjustable self-adaptive vibration attenuation and buffering can be achieved under the condition of vibration impact, various vibration and impact scenes can be solved, and the damper isflexible in structure and wide in application range.

Description

technical field [0001] The present invention relates to the technical field of dampers, in particular to an adaptive damper and a device based on the damper. Background technique [0002] The friction damper is one of the various dampers widely studied at home and abroad. Since the end of the 1970s, in order to meet the energy consumption and vibration reduction requirements of different building structures, engineering researchers have developed a variety of different types of dampers. The friction damper in this form is not only used in new passive control structures in many countries, but also in the anti-vibration reinforcement of structures and in improving the anti-vibration performance of wooden structures. [0003] Friction damper is a kind of friction force generated by the relative motion of the friction surface in a pressurized environment, so that the external input energy is converted into other forms of energy, so as to realize the change of the motion state of...

AI Technical Summary

Problems solved by technology

The traditional friction damper is to give the friction surface a certain amount of preload by means of high-strength bolts and interference contact. When the shock or vibration comes, the friction surface overcomes the sliding friction and generates relative motion, so as to achieve the purpose of energy consumption. Due to the fixed pressure between the friction surfaces of the traditional friction damper, the friction adjustment of the friction damper can buffer or adjust the magnitude of shock and vibration constant, which cannot meet the current actual needs

[0004] Patent document CN209130098U discloses a novel spring damper and a socket cover structure containing the spring damper. The novel spring damper includes a damping frame and a spring. The damping frame includes a limiting plate and a In the middle of the side end surface and protruding outward, one end of the spring is sleeved on the outer periphery of the extension, and the outer diameter of the spring is smaller than the size of the limiting plate; the spring is in a non-compressed state The axial length is greater than the length of the extension; the center of the extension is provided with a through hole through the damping frame in the axial direction, but when this design is subjected to a strong impact, the buffer structure is single and the impact resistance is poor
