The three-dimensional shock isolation and anti-swing device with self-balance, and the method are mainly applied to a design and manufacturing occasion.

Description

technical field [0001] The invention belongs to the field of civil engineering and mechanical engineering and the field of shock isolation technology, and in particular relates to a self-balancing three-dimensional shock-isolation anti-sway device and method. Background technique [0002] my country is a big country in the world, geographically located between the two major seismic belts of the Pacific Rim and the Eurasian seismic belt. Almost all regions have experienced destructive earthquakes of magnitude 6 or above. The disasters and consequences caused by the earthquake are very serious. Therefore, in order to eliminate and weaken the huge threat to people's lives and property caused by earthquakes, it is very important to design a safe, reliable, easy to use, easy to maintain, and low-cost shock isolation device. At present, the research and development of horizontal seismic isolation technology is relatively mature, and many scholars and experts have carried out resea...

AI Technical Summary

Problems solved by technology

Due to the relatively greater vertical stiffness of the structure, it is difficult for ordinary shock-absorbing measures (such as various dampers) to play an effective role

At the same time, when an earthquake strikes, as each support point of the building moves up and down, the structure will sway irresistibly, which will cause the building to sway. The damage of such swaying to the building will become more serious as the building height increases. It can be seen that it is necessary to develop a three-dimensional isolation device that can simultaneously achieve horizontal and vertical isolation and suppress structural sway
