Abstract:
1. A vibration damping device for suppressing vibrations of a structure, the vibration damping device comprising: a slide body mechanism having at least a pair of slide bodies facing each other in an opposed manner, the slide bodies being directly or indirectly fixed to the structure and being arranged so as to be slidable relative to each other in a reciprocating manner; and a biasing means for applying a compressive force which pushes the slide bodies to each other; wherein one pair among said at least one pair of slide bodies, comprises: a first slide body configured to be directly or indirectly fixed to a first part of the structure, and having a first slide surface; and a second slide body configured to be directly or indirectly fixed to a second part of the structure, and having a second slide surface in contact with and facing the first slide surface, the second slide surface being arranged so as to be slidable in a reciprocating manner along the first slide surface; and wherein the slide body mechanism is configured to have a height that varies depending on relative position of the first slide surface along the second slide surface; wherein each one slide body of the first slide body and the second slide body has a neutral position at which the slide body mechanism has a first height; wherein said each one slide body is configured so that when said vibrations of the structure act on said one slide body causing relative sliding motion among said first slide body and second slide body, said height of the slide body mechanism changes to a second height different from the first height and said compressive force of the biasing means changes; and wherein a direction of said reciprocating sliding differs from a direction of said compressive force.
