Dynamic behavior of a rotating delaminated composite beam including rotary inertia and shear deformation effects [PDF]
A finite element (FE) model is developed to study the free vibration of a rotating laminated composite beam with a single delamination. The rotary inertia and shear deformation effects, as well as the bending–extension, bending–twist and extension–twist ...

VIBRATION FREE 4.5 K SORPTION COOLER [PDF]
At the University of Twente, a breadboard 4.5 K sorption cooler was developed under ESA contract. It has no moving parts and, therefore, is essentially vibration-free. Moreover, it has the potential of a very long life. This cooler is a favorite option for missions such as ESA's Darwin mission, which is a future space interferometer consisting of a few

Experimental Study on Robustness of an Eddy Current-Tuned Mass Damper
In this paper, an eddy current tuned mass damper (ECTMD) is utilized to control the vibration of a cantilever beam. The robustness of the ECTMD against frequency detuning is experimentally studied in cases of both free vibration and forced vibration. The
