Untangling energy dependent radiation damping and chemical interface damping in gold nanorods
… practical applications. Specifically, radiation damping and chemical interface damping are crucial in plasmonic sensing and plasmon-enhanced optoelectronics. However, in systems where it is desirable to study both radiation and chemical interface damping, these terms can become entangled due to …

Extracting damping ratios using wavelets
… evaluate the accuracy of methods for extracting damping ratios with respect to: three extraction methods, different damping ratios, added noisy data, separated modes and close modes. To achieve this goal, a simulated analytical signal is analyzed by estimating the modal parameters. The simulated …

A simplified representation of damping force in lumped-parameter systems with linear and nonlinear damping
… analysis techniques which determine the damping coefficients for each sub-system in the mathematical model of linear multi-degree-of-freedom systems, and to determine modal dissipation functions for nonlinear systems. For the purpose of this study, typical aerospace vehicle structure is …

Semi-active damping of heavy vehicles.
… valve is used to generate the variable damping coefficient and the detrimental effects of the oil flow forces acting on the valve spool are studied. The force tracking performance of the damper is then examined for simple input conditions and the compliance of the hydraulic fluid is …

Damping optimization using transfer function criteria
… this paper focuses on the impact of additional damping in a 2-D frame. Finally, the method developed by Izuru Takewaki was studied and implemented. By looking at the limitation of the interstory drift, the algorithm produced the optimal distribution of the damping. In order to estimate the …

Passive damping of a LIGO mirror
There may be largely untapped source of information about our cosmic surroundings in the form of gravitational radiation, predicted by Einstein's theory of General Relativity. If detected, gravitational waves (GWs) could become a valuable means to study astrophysical events. The Laser …

Internal Damping Rates of Construction Cranes
… Previous research developed a tuned mass damping system, that effectively attenuated the energy of a pendulating payload. In order to be effective the internal damping rate of the tuned mass damper must be at least twice that of the system to be damped. Prototypes of a tuned mass damping …

Controllable, non-oscillatory damping for deformable objects
… presents a new method for the controllable damping of deformable objects. The method evolves from physically based techniques; however, it allows for non-physical, but visually plausible motion. This flexibility leads to a simple interface, with intuitive control over the behaviour of the …
