摘要：The inventive viscous damping tube stabilizer includes modules or capsules
containing a viscous material. Adjacent capsules are linked end to end by a flexible cable,allowing the device o pass through curves such as the U-bend regions of steam
generator tubes. The weight of the entire assembly will keep it essentially connected to the tube inner diameter such that any tube vibration is transmitted to the stabilizer. The viscous material may only partially fill the capsules such that even under small motion the material can slip and slide past each other, and/or bump into walls, each microscopically absorbing some of the tube energy. By creating multiple cells inside the capsule, the capsule then have good operating characteristics no matter to what angle the individual capsule is oriented as it rests on the full U-bend. The viscous material may completely fill the capsules, which also have a perforated member positioned therein. Relative movement of the capsule and disc causes the viscous material to pass through the perforations, providing damping resistance to the movement.
