Damper is a device that provides movement resistance and consumes movement energy. Using damping to absorb energy and reduce impact is not a new technology. In the aerospace, aviation, military, automotive, and other industries, various dampers (or shock absorbers) have been used to damp and dissipate energy. Since the 1970 s, people have gradually transferred these technologies to structural projects such as buildings, bridges and railways, and their development has been very rapid. Especially in the hydraulic viscous damper, which has a history of more than 50 years, before it was accepted by the American structural engineering community, especially during the long earthquake process, a lot of experiments, rigorous review and repeated demonstration tests have been carried out. A damper is a device that can quickly stop the movable part of the instrument in a stable deflection position. In seismic instrumentation, one-way dampers are used to absorb the inherent vibration energy of a vibrating system, and their damping force is usually proportional to the speed of the vibrating system. One-way damper There are three main types of liquid dampers, one-way damper gas damper and electromagnetic damper. One-way dampers play an important role in compensating for small friction and air resistance in the vibration sensor pendulum system and improving the frequency response.
Various frictions and other obstacles that weaken free vibration are called damping. The "special" components placed on the structural system by the damper can provide movement resistance and consume movement energy. We call them one-way dampers. The damper is also called a damping device. A device that increases damping so that the vibration generated during impact is quickly attenuated. An ideal one-way damper is an oil damper. Commonly used one-way damper oils include silicone oil, grate oil, mechanical oil, diesel oil, engine oil and transformer oil, which can be made into plate type, piston type, square cone, cone, etc. Others include solid viscous dampers, air dampers and friction dampers. One-way damper According to the actual needs of vibration isolation design, damping ratio D = 0.05~0.2 is preferred. The
damper is a device that provides resistance to movement and consumes movement energy. In the aerospace, aviation, military, guns, automobiles and other industries have been applied a variety of dampers (or shock absorbers) to reduce vibration and energy dissipation. Since the 1970 s, people have gradually transferred these technologies to buildings, bridges, railways and other structural projects, and their development is very rapid. In particular, the hydraulic viscous damper with a history of more than 50 years has undergone a large number of experiments, rigorous review, and repeated demonstrations before it was accepted by the structural engineering community in the United States, especially the long process of seismic testing.
