Increasing Damping Ratios in a Tuned Liquid Damper Using Damping Bars

Key Engineering Materials, 2007
Wind-induced vibration of tall buildings have been of interest in engineering for a long time. Wind-induced vibration of a tall building can be most effectively controlled by using passive control devices. The tuned liquid damper(TLD) is kind of a passive mechanical damper, which relies on the sloshing liquid in a rigid tank.

On damping ratio of polynomials with perturbed coefficients

IEEE Transactions on Automatic Control, 1992
C.B. Soh and C.S. Berger (1988) derived a sufficient condition for a family of interval polynomials to have a damping ratio of phi using Kharitonov's theorem for complex polynomials. This paper points out that the transformations used by Soh and Berger to obtain the sufficient conditions also guarantee a simplification of Kharitonov's theorem for ...

The damping ratio of an optimal control system

IEEE Transactions on Automatic Control, 1965
Optimal control theory is used to design a second-order linear control system with step response that is, in a certain sense, the best possible. The damping ratio of this optimal system is compared with the value (1/\sqrt{2}) of damping ratio that is conventionally assumed to give good performance. For a special class of second-order controlled objects,

A frequency domain interpolation method for damping ratio estimation

2014 IEEE International Conference on Control System, Computing and Engineering (ICCSCE 2014), 2014
Damping ratio is usually needed for structure dynamics analysis. To improve the accuracy of damping ratio estimation and make it benefit for engineering application has been a difficult problem. A new method for the estimation of damping ratio which is necessary for structure dynamics analysis is presented.

Improved Method for Evaluating Damping Ratios of a Vibrating System

AIAA Journal, 1993
This note aims to simplify the method of \textit{D. Inman} and \textit{B. Jiang} [Int. J. Anal. Exp. Modal Analysis 2, No. 1, 38-42 (1987)] and to extend it to nonsymmetric systems. In addition, mode truncation is also addressed.
