Damper is a device that provides movement resistance and consumes movement energy. Damper is a very important component, developing rapidly and widely used. Today, let Xiaobian introduce the development process and application of dampers!
20 century, especially in the past 20 or 30 years, people have made great efforts to improve the anti-vibration ability of buildings, and achieved remarkable results. This achievement is very proud of the "structural protection system". People jump out of the traditional concept of strengthening beams, columns and walls to improve the anti-vibration ability, and combine the dynamic performance of the structure to skillfully avoid or reduce the damage of earthquakes and wind. The base isolation of high-rise building roofs, various energy dissipation systems, mass resonance damping systems and active control damping systems have all been put into engineering practice. Some have become indispensable protective measures to reduce vibration. Especially for unpredictable earthquakes and multi-dimensional vibrations, the damage mechanism is not very clear, and the protection system of these structures is even more important.
The development process and application of dampers
These structural protection systems are less controversial, and beneficial and harmless systems should use dampers to absorb unpredictable seismic energy. Damping to absorb energy and reduce vibration is not a new technology. Various dampers have been used to reduce vibration and dissipate energy in the aerospace, military industries, firearm, automotive, and other industries. Since the 20th century 70 s, people have gradually applied these technologies to buildings, bridges, railways and other projects, and they have developed very rapidly. By the end of the 20th century, there were 100 structural projects around the world using dampers to absorb energy and shock.
I believe everyone will know the development process and application of dampers after reading this article. Do you want to know other knowledge about dampers? Welcome to continue to pay attention to our other introductions about dampers.
