Seismic Performance of Tuned Mass Dampers

2010
In 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, 2006
A 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 ...

Re-tuning tuned mass dampers using ambient vibration measurements

Smart Materials and Structures, 2010
Deterioration, accidental changes in the operating conditions, or incorrect estimates of the structure modal properties lead to de-tuning in tuned mass dampers (TMDs). To restore optimal performance, it is necessary to estimate the modal properties of the system, and re-tune the TMD to its optimal state.

Output-only de-tuning assessment of tuned mass dampers

Journal of Civil Structural Health Monitoring, 2012
In this paper, an algorithm to assess the de-tuning of tuned mass dampers (TMD) while in operation is proposed. De-tuning of such smart structures occurs due to several reasons such as accidental changes in operating conditions or deterioration of the current modal properties which leads to significant loss of its performances.

Supertall buildings with tuned mass damper

The Structural Design of Tall Buildings, 1994
AbstractThis paper introduces the ‘mega structure’ concept for supertall buildings. This concept incorporates the latest technology for structural energy dissipation and control systems, which are capable of predicting, controlling and modifying building motion/response.

Adaptive tuned mass damper concept

2008
A 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 ...

Optimal Tuned Mass Dampers for Buildings

Journal of the Structural Division, 1979
This 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 ...

Adaptive tuned mass damper boring tool

2020
Single point boring of highly slender workpieces with internal features requires vibration damped tooling to avoid unwanted chatter vibrations. The tuned mass damper (TMD) boring tool has made machining of these highly slender features possible by increasing the dynamic stiffness and therefore the chatter stability of the cantilevered tool.
