PASSIVE DAMPING OF SPACECRAFT SANDWICH PANELS [PDF]

, 2007
For reusable and expendable launch vehicles as well as for other spacecraft structural vibration loads are safety critical design drivers impacting mass and lifetime. Here, the improvement of reliability and safety, the reduction of mass, the extension

Stability Boundary for Haptic Rendering: Influence of Physical Damping. [PDF]

, 2006
Physical damping is increasing the z-width of haptic simulations. This paper derives the normalized stability boundaries for physically damped one degree of freedom haptic devices colliding with a virtual wall represented as spring-damper system.

Ground‐State Charge‐Transfer Doping in Donor–Acceptor Semiconducting Polymers

Advanced Functional Materials, EarlyView.
This work demonstrates controlled ground‐state charge‐transfer complex formation (GS‐CTC) and doping in a series of diketopyrrolopyrrole‐based donor–acceptor semiconducting polymers paired with a π‐conjugated penta‐t‐butylpentacyanopentabenzo[25]annulene “cyanostar” macrocycle. Complementary experimental techniques show how subtle molecular, electronic,

Damping of kink waves by mode coupling. II. Parametric study and seismology [PDF]

, 2013
Context: Recent observations of the corona reveal ubiquitous transverse velocity perturbations that undergo strong damping as they propagate. These can be understood in terms of propagating kink waves that undergo mode coupling in inhomogeneous regions ...

Aseismic performances of constrained damping lining structures made of rubber-sand-concrete

Journal of Rock Mechanics and Geotechnical Engineering
Flexible damping technology considering aseismic materials and aseismic structures seems be a good solution for engineering structures. In this study, a constrained damping structure for underground tunnel lining, using a rubber-sand-concrete (RSC) as ...

Analysis of Vibration Reduction by Damping Using Simple Analytical Modelling

Shock and Vibration, 2018
The performance of different solutions to global vibration reduction using external damping is discussed. The solutions are either uneven distribution of structural damping or use of vibration absorbers.

Stiffness and Damping Properties of LPBF-Fabricated TC4 Alloy Beams Incorporating Self-Sealing Powder and Lattice Structures

Metals
Laser powder bed fusion (LPBF) provides an effective method for the preparation of self-sealing powder damping components, but the introduction of cavities simultaneously leads to a decrease in the mechanical properties of the components.
