With the development of the city, more and more skyscrapers are rising in the city. The number of these skyscrapers has become one of the criteria for measuring the economic development of a city. More and more, these skyscraper complexes have also become city landmarks, and people can think of a city whenever they mention a certain building.

For example, Shanghai Finance Building, Guangzhou's Xiaoman waist, Taipei's 101 Building, etc., are all very famous skyscrapers and landmarks of these cities. However, when someone visited the Taipei 101 Building, they found it inside the building. There are several floors with a very small space, and there is also a huge iron ball hanging inside.

Typhoons can cause great damage to buildings. A strong typhoon can lift the roof of a house. To turn over, and tall skyscrapers are very dangerous when they encounter typhoons. If they are not careful, skyscrapers will face the risk of "waist folds". Therefore, when building skyscrapers in Taiwan, the typhoon-stricken area, it is necessary to consider the typhoon factor. After many typhoons, the Taipei 101 building still stands still because of this big iron ball.

The scientific name of this big iron ball is tuned mass damper, or wind damper for short. Its function is to offset most of the shaking effect of the wind on the building when the typhoon is coming, so that the building can still stand in the strong wind. When the wind damper encounters strong wind, the sensor will introduce the wind and wind direction into the sphere. At this time, the sphere will continue to shake in the opposite direction of the wind direction under the control of the joystick. The greater the wind, the greater the magnitude of the shaking In order to stabilize the building and reduce its left and right shaking feeling, the installation of wind dampers is very important for skyscrapers.

When many people see this big iron ball when they visit the skyscraper, they first marvel at its hugeness, and then worry about what to do if it falls. Like the wind damper in the Taipei 101 building, which weighs 660 tons, if it falls If you come down, you will smash through the building directly to the basement, so everyone is very scared. However, there are 8 steel cables on it, and 200 metal cables pull it, so its security is still high and it will not fall off easily.
