Discrete Distributed Tuned Mass Damper
2020Tuned Mass Damper (TMD) is a passive device that conducts vibration energy exchange through tuning and is used to control the vibration of the main vibrating body. Its applications include controlling the low frequency vibration of bridges, ship mast jitter, auxiliary vibration energy transmission, and the noise leakage control of floating raft ...

Seismic Performance of Tuned Mass Dampers
2010In a fundamental parametric study the seismic performance of Tuned Mass Dampers(TMDs) is investigated. Earthquake excited vibration-prone structures are modeled as elastic single-degree-of-freedom oscillators and they are equipped with a single TMD. The TMD performance is assessed by means of response reduction coefficients, which are generated from ...

Brake assembly with tuned mass damper
The Journal of the Acoustical Society of America, 2006A tuned mass damper for sound-dampening brake squeal noise is located within a hole formed in a brake component such as a backplate supporting a brake pad. The location of the hole and the weight and geometry of the tuned mass damper are tailored to provide effective damping for the particular frequencies that are to be eliminated in the brake system ...

The Journal of the Acoustical Society of America, 2011
A spare tire tuned mass damper assembly is provided for reducing vehicle vibration or beaming shake that may otherwise be perceptible at the driver interface. The assembly is attachable between a pair of underbody support beams and includes a tire carrier for a spare tire and wheel and a plurality of spring and damper assemblies positioned between the ...

A method for tuning tuned mass dampers for seismic applications
Earthquake Engineering & Structural Dynamics, 2012ABSTRACTThis paper studies tuned mass dampers (TMDs) resulting in high modal damping for mechanical systems incorporating such devices for the purpose of seismic response reduction. Focusing on the determination of damping and tuning, the proposed methodology identifies a point of multiplicity of complex eigenvalues and eigenvectors, resulting in ...

Optimal Tuned Mass Dampers for Buildings
Journal of the Structural Division, 1979This note has presented approximate formulas for the design of a TMD system. For most buildings, the accuracy obtained from the closed form expressions is adequate for preliminary design. This note has also shown, using results of the feasibility study of the Citicorp Center TMD, that the effective damping of a building with a TMD is smaller than ...

Frequency Analysis of the Tuned Mass Damper
Journal of Applied Mechanics, 2005The damping properties of the viscous tuned mass damper are characterized by dynamic amplification analysis as well as identification of the locus of the complex natural frequencies. Optimal damping is identified by a combined analysis of the dynamic amplification of the motion of the structural mass as well as the relative motion of the damper mass ...

Adaptive tuned mass damper concept
2008A tuned mass damper is a well known concept that can be used to reduce undesired oscillation of structures. In the structures where the dynamic properties are changing with time an adaptation of the tuning is needed. In this study two complementary concepts for the adaptive tuned mass damper (ATMD) were studied based on utilization of ...
