They are frequently used in power transmission, automobiles, and buildings. Did you know you can tune a skyscraper just like a guitar?

Contrary to popular intrinsic belief, skyscrapers and other . They are especially suitable to be used in flexible structures affected by external phenomena characterized by a range of disturbance frequencies such as to interfere with the own frequency of . Tuned mass dampers , also known as TM are one of the many types of anti- vibration systems manufactured by FIP INDUSTRIALE. A tuned mass damper (TMD) is a device consisting of a mass, a spring, and a damper that is attached to a structure in order to reduce the dynamic response of the structure. The frequency of the damper is tuned to a particular structural frequency so that when that frequency is excite the damper will resonate out of phase . Description: A high frequency TMD is a additional damping device which is used in various mechanical applications.

De très nombreux exemples de phrases traduites contenant tuned mass damper – Dictionnaire français-anglais et moteur de recherche de traductions françaises. A tuned mass damper is a device mounted in structures to prevent discomfort, damage, or outright structural failure caused by vibration during earthquakes.

A review of representative research on tuned massed dampers (TMD) reported in journals in recent years is presented. TMDs are divided into four categories: conventional TMDs, pendulum TMDs (PTMDs), bi-directional TMDs ( BTMDs), and tuned liquid column dampers (TLCDs). ENERGY TRANSFER TO A COUPLED OSCILLATING SYSTEM – ABSORPTION. By that the amplitude of the vibration of the original system can be reduced significantly.

Tuned Mass Damper ( TMD ) consists in simply two tubular rings on the suspension. They stabilise the dynamic behaviour of the surround according to resonance, thus avoiding deformation of the cone without afflicting the dynamics. The use of GERB tuned mass dampers can significantly reduce low natural frequencies. We provide analysis and design for tuned mass dampers (TMD) in tall buildings, long-span structures and bridges. The review essentially focuses on the response control of wind- and earthquake-excited structures and covers theoretical backgrounds of the TMD and research developments therein.

Typically, the tuned mass dampers , a kind of seismic vibration control technology, are huge concrete blocks mounted in skyscrapers or other structures and moved in opposition to the resonance frequency oscillations of the structures by means of some sort of spring mechanism. So what can engineers do to reduce this movement, but preserve the flexibility of the building? Enter tuned mass dampers (previous coverage).

Traductions en contexte de tuned mass dampers en anglais-français avec Reverso Context : One or more tuned mass dampers are connected to the housing. This device adds mass, as in a traditional solution—but here the mass moves. This movement is passive, requiring no electricity or computer system to control it.

Multiple tuned mass dampers (MTMDs) distributed along height of a high-rise building are investigated for their effectiveness in vibration response control. A -storey benchmark building is modeled as shear type structure with a lateral degree of freedom at each floor, and tuned mass dampers (TMDs) are .

It is known that the effectiveness of tuned mass dampers (TMDs) decreases as the input duration shortens. As a result, their use is commonly discouraged against short-duration, pulse-like ground motions, such as those occurring in near-field (NF) zones in the presence of forward directivity or fling-step effects. When installed properly on a machine or structure, they draw away vibrational energy from the structure or machine and dissipate it internally, reducing the motion of the machine. Tuned vibration absorbers, or TVAs, are undamped .
