Brief Introduction Of The Development Process Of Small Rotary Dampers

- Aug 26, 2017-

             As you know, all kinds of friction and other inhibiting effects of free vibration decay, we call it damping. The "special" components placed on a structural system can provide resistance to movement, a device that consumes less energy, and is called a damper.Small Rotary Dampers

             The use of damping to absorb energy absorption is not a new technology, in aerospace, aviation, military, guns, automobiles and other industries have already applied a variety of dampers (or shock absorbers) to reduce energy dissipation. Since the the 1970s, people began to gradually switch these technologies to construction, bridges, railways and other structural projects, its development is very rapid. In particular, the more than 50-year-old hydraulic viscous damper, before the United States by the structural engineering industry accepted, experienced a large number of experiments, rigorous review, repeated argumentation, especially the long process of earthquake test. The process shown in the following process 1 outlines its evolution in the United States:Small Rotary Dampers

             In aerospace, aviation, military, machinery and other industries widely used, decades of successful application of the history; in the 80 's, two earthquake research centers in the United States and other units have done a lot of experimental research, published dozens of papers; The 90 's, the National Science Foundation and the Civil Engineering Society and other units organized two large-scale joint, by a third party to make a comparative test, gave the authoritative test report, for professors and engineers to reference; The normative review, affirmed and stipulated the application method, the Management department passed, has brought the hundreds of structural engineering practical application. These structural engineering, successfully experienced the earthquake, gale and other disaster test, very successful.Small Rotary Dampers
