This clearly indicates that the same damper damping is not required in all the dampers and can be going on reducing from the top-most damper to the bottom-most damper in the same variation as the maximum relative velocity in the connecting floors varies.
The sluggish business climate is simply too much of a damper to provide any hope that this summer's busy travel season has legs beyond this Labor Day, which falls on the earliest possible date for the holiday.
But the developers of that project, as in many others, opted to sacrifice space near the top of the building and incur extra costs for the installation of a tuned mass damper to have an extra margin of comfort, Mr. Poon said.
When Olympus released the OM-1 in 1973, it was hailed for being so small and light; the developments made to achieve this included replacing tiny brass fittings with rust-proof steel ones, and installing an air damper to reduce noise.
"Among the few things which I chanced to say," Thoreau reported, "I remember that one was, in answer to him as representing America, that I did not think much of America or of politics, and so on, which may have been somewhat of a damper to him".
The application of an ER damper to a Laval rotor system was studied.
The objective of this paper is to optimize geometric parameters of an MR damper to have its optimized damping performance.
This paper proposes a new innovative passive viscoelastic damper to reduce floor vibrations.
This work is done by adding an eddy current passive damper to a semi-active MRD.
In this approach, force-feedback loops were used to induce a MR damper to produce approximately a desired control force.
The results of numerical analyses suggest the use of a tuned mass damper to enhance the building performances.
