Abstract
A shear viscous damped hinge uses a negator spring and a high viscosity fluid to provide a relatively slow and controlled deployment of the hinge. Shear damping of the fluid slows the angular velocity of the hinge. The invention reduces the end of travel impact loads thereby reducing the risk of damage to the hinge and the object rotated by the hinge. The hinge is particularly useful in, but not limited to, spacecraft applications.
