Combined with the energy characteristics of the structure, earthquakes and wind damage are avoided or increased wonderfully. Basic isolation (basic isolation), various applications of shock absorbers, energy absorption, energy dissipation system, mass resonance damping system (TMD) and conACE MA 150MEtrol (active control) damping system for high-rise building roofs have been obtained in engineering practice The application. Some have become increasing vibrations-an indispensable protective measure.
Certain application methods of dampers. • Adopted by the governance department, brought hundreds of damping structural engineering practices. These structural projects, successful experiences, and earthquake disaster tests are very popular. In the twentieth century, especially in the past two years, more than thirty people have made great efforts in building anti-vibration capacity and achieved significant results. What is proud of is the "cover structure system". People jump out of the traditional view of stiffeneACE MA 150MEd beams, columns, walls, and improved vibration resistance.
Since the 1970s, people have gradually applied shock absorbers to construction, bridge, and railway construction projects, and their development has been very rapid. Especially, hydraulic viscous dampers have a history of 50 years. The Inussa project received before construction has undergone a lot of experiments, harsh reviews, and repeated demonstrations, especially the long history of earthquake testing. • Damper is widely used in aerospace, aviation, machinery and other industries.
Few people know about ACE dampers. Dampers are an obstacle to installation friction and so on: free vibration attenuation, which we call damping. The "special" components placed in the structural system can provide motion resistance and energy consumption devices. The application of dampers to absorb energy consumption is not a new technology. It is widely used in aerospace, aviation, automotive, and other industries-the dissipation of vibration energy by dampers (or shock absorbers).
The "special" components placed on the structural system can provide resistance to movement and reduce energy consumption. We call it a damper. Damper is also called damping device. A device for increasing damping in order to quickly attenuate vibrations generated when impacted. The ideal damper is an ACE oil damper. Common oils are silicone oil, ramie oil, mechanical oil, diesel oil, motor oil, aACE MA 150MEnd transformer oil. Its form can be made into plate type, piston type, square cone, cone, etc. Others include ACE solid viscous dampers, ACE air dampers and ACE friction dampers. According to the practical requirements of vibration isolation design, the damping ratio D = 0.05 ～ 0.2 is better.
The damping force is generally proportional to the speed of the vibration system. There are three types of ACE liquid dampers, gas dampers and electromagnetic dampers. The damper plays an important role in compensating the small friction and air resistance in the vibration system of the pickup and improving the frequency response. As we all know, the various frictions and other obstacles that attenuate free vibrations are called damping.
Its development is very rapid. Especially the hydraulic viscous damper with a history of more than 50 years, before it was accepted by the structural engineering community in the United States, it has undergone a lot of experiments, rigorous review, and repeated demonstrations, especially the long process of earthquake tests. A device capable of quickly stopping the movable part of the meter in a stable deflection position. In seismic instruments, a damper is used to absorb the natural vibration energy of a vibration system.
It makes ACE unable to achieve collision and loses the function of damping vibration by collision. This example reminds us that in the design process of ACE, we should consider the matching between the diameter of the impactor, the diameter of the particle damper and the internal diACE MA 150MEameter of the ACE to avoid the phenomenon of the impactor and the particles getting stuck in the ACE. 1) Collision damping with particle damping agent has good damping performance.
