Sensorless action-reaction-based residual vibration suppression for multi-degree-of-freedom flexible systems [PDF]
, 2010 This paper demonstrates the feasibility of controlling motion and vibration of a class of flexible systems with inaccessible or unknown outputs through measurements taken from their actuators which are used as single platforms for measurements, whereas ...

Free Vibration Analysis of Rings via Wave Approach
Shock and Vibration, 2018 Free vibration of rings is presented via wave approach theoretically. Firstly, based on the solutions of out-of-plane vibration, propagation, reflection, and coordination matrices are derived for the case of a fixed boundary at inner surface and a free ...

VIBRATION FREE 4.5 K SORPTION COOLER [PDF]
AIP Conference Proceedings, 2008 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
