Smart double panel with decentralised active dampers for control of sound transmission

, 2007
This report presents the results of a theoretical study of active sound transmission control through a double panel. The double panel material and geometrical properties have been chosen so as to emulate section of an aircraft fuselage, or bodywork of a ...

Leg prosthesises with active damping

Journal of Dynamics and Vibroacoustics
The article considers various types of leg prosthesises with active damping based on pneumatic, hydraulic and electric drives. For each type of drive used, its advantages and disadvantages, features of design solutions were described with the aim of further selecting a prototype from existing knee modules of leading manufacturers to develop a domestic ...

A note on the effect of surface contamination in water wave damping [PDF]

, 2000
Asymptotic formulas are derived for the effect of contamination on surface wave damping in a brimful circular cylinder; viscosity is assumed to be small and contamination is modelled through Marangoni elasticity with insoluble surfactant. It is seen that

Reduced joint models for damping design of multi-jointed structures [PDF]

, 2014
− Design of damping in multi-jointed structures is studied here. − Dissipation sources are viscoelastic behavior and contact/friction at joints interfaces. − Reduction on meta-models of nonlinear joints models is investigated.

Active Damping of a Flexible Beam

, 2004
This paper describes the active damping of a flexible beamconnected to the end-effector of a robot manipulator. An observer-basedfeedback controller is developed and experimental results arepresented. Iterative feedback tuning (IFT) is applied to shape the step response.
