Abstract

The invention discloses a multifunctional shock absorber with an energy recovery function. The multifunctional shock absorber comprises an upper barrel and a lower barrel, wherein the upper barrel is divided into a middle cavity and a functional cavity which communicate with each other, and the middle cavity is filled with air springs; a mass block piston is arranged in the functional cavity and is connected with the inner wall of the upper barrel through a spring; the lower barrel comprises an inner barrel and an outer barrel, and two permanent magnets are mounted on the inner side of the outer barrel; the inner barrel is divided into a middle cavity and functional cavities which communicate with each other, and the middle cavity is located in the center of the inner barrel and is filled with air springs; the functional cavities are located around the middle cavity; metal blades are arranged between every two adjacent functional cavities; each functional cavity is divided into four small cavities, an energy collecting device and a rotating wheel are arranged in each small cavity, each small cavity is filled with magnetorheological fluids, air springs and lead screw nut pairs, and screw rod pieces of the lead screw nut pairs penetrate through the four cavities and are connected with the two ends of the functional cavities; and the two middle cavities are connected through a bearing.

Description

technical field

[0001] The invention relates to the field of vibration control of civil engineering, in particular to a multifunctional shock absorber with energy recovery, which is mainly used to reduce the vibration response of towering or long-span space structures under the action of environmental excitation. Background technique

[0002] Due to the widespread use of lightweight and high-strength materials, new high-rise building structures usually have the characteristics of light weight, high strength, large aspect ratio, and low natural vibration frequency; therefore, these high-rise buildings are dynamic to the environment (such as wind, waves, Earthquakes, etc.) are becoming more and more sensitive. Under the excitation of monsoons and typhoons, the wind-induced vibration damage of high-rise buildings, the discomfort of residents in the buildings and the damage of living facilities are becoming more and more serious. It has become an urgent and important task for e...
