“…Rittweger et al [19] investigated passive damping devices for space structures based on the physical principles of coulomb friction, hydrodynamic and hydraulic concepts and viscoelas-tic bushings. Pamley et al [20] compared the effectiveness of different methods of applying passive damping such as extensional, constrained layer and viscosphere in-fill to hollow structures.…”

Traditional large space structure construction incorporates the use of light-weight tubular metal alloys which have good strength to weight and stiffness to weight ratio.Recently, however, space structure construction has shifted focus on materials that are ultra light-weight, have high strength, have low package volume and possess excellent damping characteristics. Substantial damping is required in space since there is no surrounding medium to provide damping. Such a construction uses composites in a fabric form that displays viscoelastic behavior. The viscoelastic behavior is attributed to energy dissipation because of the shear stresses between the various fibrous strands that are kept in place by constraining viscoelastic layers. This type of vibration control falls under the rubric of passive damping of structures and has been found to have certain advantages over active damping such as less complexity as it does not require sensors, actuators and power supply that are needed for active damping.

“…Additionally, it has the advantages of high reliability and good economic benefits. Moreover, A Rittweger et al 10 researched four different damping principles for the corresponding damper device predesign. These principles were based on the following physical effects: hydrodynamic concept, hydraulic concept, coulomb friction, and viscoelastic bushings.…”

With the space technology development, large flexible space deployable structures have been used widely. Studying on the vibration control for large flexible space deployable structures becomes very important. In this study, a novel passive vibration damping device is developed for the multi-panel sun-orientated deployable solar array. Its upper strut contains a viscous damper while the lower strut is rigid. The device is lockable and located near the solar array root hinge to increase the structural damping without reducing the fundamental frequency. This design will not influence the original functions of the solar array, such as folding, deploying, and sun tracking. The corresponding finite element models are established, and the properties of the damping device are investigated by modal analysis and transient response analysis. The damping mechanism design for a certain type of solar array is presented. The associated modal tests based on a solar array test sample verify the effectiveness of the device. Conclusions are drawn to help define design guidance for future damping device implementations.

“…These dissipate a large portion of the input energy to mitigate shock and vibration for the protection of the main structure. In recent years, significant effort has been directed toward the development of fluid viscous dampers for structural applications, in which they can be effectively employed in order to achieve the desired level of passive control and absorb almost all of the disturbing energy, leaving the structure intact and ready for immediate use after an event [1][2][3][4][5].…”

“…where f damping is the damping force, C is the damping coefficient, which depends on the physical dimensions and the damping materials [4], v is the velocity of the piston with respect to the cylinder, and n is a real positive exponent characterizing the nonlinearity of the damper. The range of the nonlinear exponent n described by different authors is different.…”

A basic design method of doubly acting fluid viscous dampers with double guide bars is presented. The flow of the viscoelastic fluid between two parallel plates, one of which is started suddenly and the other of which is still, is analyzed. According to this solution, the velocity and the shear stress of the fluid at the fringe of the piston are solved approximately. A mathematical model of viscous dampers is derived, and the shock test is carried out. From experimental results, the parameters of the mathematical model are determined. Consequently, a semi-empirical design equation is obtained. Applying this equation to a certain practical damper, the damping material is chosen and the physical dimensions of the damper are determined. Shock tests using this damper are performed. Theoretical results are in good agreement with experimental results, which validates the reliability of the calculated physical dimensions of the specimen damper and the validity of the basic design equation.
