What is the working principle and classification of damper damper

What is the working principle and classification of damper damper What is the damper Damper, is to provide the motion resistance, energy depletion exercise device. And placed in the structure of the system of the "special" component can provide resistance to motion, motion device depletion of energy, we called damper. From twentieth Century seventy years later, people began to put these technical conversion to buildings, bridges, railways and other structural engineering, its development is very rapid. Especially the hydraulic viscous damper has a history of over 50 years ago, accepted structure engineering in America, experienced a large number of experiments, strict examination, repeated demonstration, especially the long process of seismic test. What is the role of the damper, damper In twentieth Century, in particular the ability of anti vibration of nearly two people, thirty years on the building's raise great efforts have been done, and achieved remarkable results. This results in the most proud of is the "protection of system structure". People jump out of the traditional reinforced beam, column, wall and improve the ability of anti vibration concept, combining the dynamic performance of the structure, ingenious and avoid or reduce the seismic and wind damage. Base isolation (Base Isolation), all using the damper (Damper) energy absorption, energy dissipation system, quality resonance damping system of high-rise building on the roof (TMD) and active control (Active Control) damping system is already to engineering practice. Some of them have already become protective measures to reduce the vibration of not less. Especially for difficult to predict earthquakes, multidimensional vibration failure mechanism is not very clear, the protection system structure is becoming more and more important. The least controversial of these structures in the protection system, the system is beneficial and harmless is making use of dampers to absorb seismic energy which is difficult to predict. The use of damping energy absorption and shock absorption is not a new technology, aerospace, military, guns, damper motor industry has a wide variety of applications to vibration energy dissipation. From twentieth Century seventy years later, people began to put these technical conversion to buildings, bridges, railway project, its development is very rapid. By the end of the twentieth Century, the world has nearly 100 more structural engineering using the damper to damping. By 2003, only Taylor company installed 110 buildings in the world, bridge or other structure building. What is the classification of damper, damper The damper is just a member. Use damping effect is different in different place or different work environment. Damper: used for vibration reduction; Snubber: used to shock, allowing mobile speed, locking in the speed or acceleration exceeds the corresponding values, forming a rigid support. At present, various applications: spring damper, a hydraulic damper, pulse damper, rotary damper, the damper, viscous damper.
