An introduction of the development process of the damper

An introduction of the development process of the damper An introduction of the development process of the damper: We know, make free vibration attenuation effect of various friction and other obstacles, we call the damping. And placed in the structural system of "special" component can provide resistance to motion, motion device depletion of energy, we called damper. The use of damping energy absorption and shock absorption is not what new technology, aerospace, aviation, military damper, guns, automotive and other industries already use a variety of (or shock absorber) to vibration energy dissipation. From twentieth Century seventy years later, people gradually began to take these technical conversion to buildings, bridges, railway construction project, its development is very rapid. Especially the hydraulic viscous damper has 50 years of history, is constructed in USA engineering circles bear before, experienced a lot of experiment, strict inspection, repeated demonstration, especially the long process of seismic test. The following process 1 shows process, summarize it in American development process: in the aerospace, aviation, military industry, machinery and other industries in wide use, decades of successful application of the history, the last century 80's began to make a lot of experimental research in USA things two earthquake research center and other units, published dozens of articles about the article, the 90's, USA National Science Foundation and the Institute of civil engineering and other units jointly organized two large-scale, comparative tests made by the third party, gives the test report of authoritative, for professors and engineers refer to, based on the above results are almost certainly the relevant agencies, specification check, and the provisions of the measures, must use management through the practical application, has brought hundreds of construction engineering. These structural engineering, successfully experienced the earthquake, wind disaster test, very successful. We provide the characteristics of damper 1 magnetic damper is also known as the tension controller, tension device or brake torque transfer device, is the preface to constant magnetic field. The damping plate and the magnet no contact, no sliding friction, so the use of long life, tension control is extremely stable. 2 installation has the advantages of simple structure, convenient to adjust the output torque. 3 structure of compact design, small size, can be in a variety of locations and stable work. Two. Magnetic damper adjustment method and the use of attention to matters 1 the proposed scale value to more than 4 customers will be using, at this time if the tension is too large, the best selection of smaller size specifications of the damper. 2 if the scale value below 4 use pulsation may produce force. Please click back 3 the way to eliminate the fluctuation. The 3 fastening screws are loosened, the scale to 10, rolling spindle slowly together will scale to 0, and then go to The required scale value determination, tighten screws. 4 if the use of tension fluctuation phenomena appear in the process, please repeat the above adjustment method of 3 steps until a satisfactory tension. 5 damper using magnet produces objective magnetic field data brittleness, so the application do not dismantle, to avoid mechanical damage.
