ABSTRACT:
A viscoelastic damper which is adapted to control the vibration of a structural member, a tank, a pipe, etc. which may be caused by an earthquake or wind while producing minimum reaction force when the structural member and so on is slowly displaced as a result of the thermal deformation of the member itself or another member connected thereto. Such a property of a viscoelastic damper can be obtained by using dilatant liquid which presents relatively small resistance when the speed of the motion is small and produces progressively great resistance as the speed of the motion increases. To the end of enhancing this favorable property of the viscoelastic damper, the shoulder surfaces that are exposed to the dilatant liquid are rounded. By providing a spiral groove or projection in the member exposed to the dilatant liquid to produce rotational motion between the two ends of the damper, this property is enhanced even more.
