Description

The present invention relates to a tuned fluid damping system (also known as tuned fluid damper, Tuned Sloshing Damper, TSD) and the technical field of fire fighting equipment, in particular to a tuned fluid damping system with shock absorbing parts and fire fighting equipment.

In recent years, with the continuous growth of the population, the demand for housing has also increased accordingly. High-rise buildings that can accommodate multiple families have gradually replaced the previous single-family villas. Countries with high population density, such as Hong Kong, often also have more High-rise buildings, and in order to accommodate more people, there are even super-high buildings with a total height of more than 300 meters. Generally speaking, taller buildings sway from side to side when encountering high-altitude strong winds, earthquakes or typhoons Therefore, architects need to consider how to install dampers to slow down the shaking of high-rise buildings when designing high-rise buildings, so as to ensure that high-rise buildings have a certain seismic capacity.

With different damping effects, it can be divided into various types of dampers. Generally, common dampers can be divided into Tuned Mass Damper and Tuned Liquid Damper. The shock absorption principle of the tuned mass damper is to change its dynamic characteristics through an oscillating system composed of mass blocks, springs and dampers. When the building itself is shaken by external force, the tuned mass damper can produce a movement direction that is different from that of the building. The opposite inertial force reduces the shaking of the building. The disadvantage of the tuned mass damper is not only the high technical level of construction, but also the mass block is generally hundreds of tons. In addition, it is not easy to manufacture springs with high rigidity. In case of emergencies, certain professional and technical personnel are required.
