Skylab viscous damper study [PDF]
The proposed magnetically anchored viscous fluid damper can maintain the Skylab in a gravity-gradient stabilized mode at the anticipated reboost altitudes. The parameters influencing damper performance (and thereby affecting the degree of risk) are: (1)

Study on the Development of Passive MR Damper with Displacement-Dependent Damping Characteristics
Journal of Fluid Science and Technology, 2010 In this paper, we propose a new concept of a magneto-rheological (MR) fluid damper, which is a passive MR fluid damper. The passive MR damper has no electrical devices, such as a sensor, power supply and controller, and hence, it has an advantage in ...

Seismic Response Mitigation of a Long-Span Tower Bridge with Two Types of Constraint System
Advances in Civil Engineering, 2020 The stress of the main tower of a cable-stayed bridge depends on the connection type between the tower and deck. In order to study the most suitable longitudinal damping mode for a long-span cable-stayed bridge.

A damper for ground wind-induced launch vehicle oscillations [PDF]
, 1975 Prelaunch oscillatory bending deflections of the Atlas/Centaur launch vehicle are restrained by a damper mechanism mounted on the end of a horizontal boom supported from the umbilical tower. A single vertical pin on the vehicle engages the mechanism, and
