Abstract:
1. A pole vibration damping assembly mountable on a vertical non-rotatable pole for damping wind induced first harmonic mode vibrations of the pole, said assembly comprising an annular housing including a horizontally oriented first housing component half-portion and a horizontally oriented second housing component half-portion horizontally aligned with the first housing component half-portion and connections connecting the first housing component half-portion to the second housing component half-portion, each housing component half-portion including an inner partial cylinder sleeve having an inner partial cylinder sleeve surface having a lower end portion, a vertical center of curvature and being dimensioned and shaped to fit in a mating manner over, and in facing contact with, an upper end portion of a vertical non-rotatable pole and having an axis approximately coextensive with the center of curvature of the pole, an outer partial cylinder sleeve positioned outwardly of the inner partial cylinder sleeve surface and having a lower end termination portion and a vertical center of curvature that is coextensive with the center of curvature of the inner partial cylinder sleeve surface, a floor panel extending between lower portions of the inner partial cylinder sleeve surface and the outer partial cylinder sleeve, a plurality of vertical partitioning panels extending vertically upward from the floor panel and extending between the inner partial cylinder sleeve and the outer partial cylinder sleeve to define non-circular damping weight receiving chambers between adjacent partitioning panels and a movable damping weight supported by the floor panel for horizontal rolling movement in each of the damping weight receiving chambers.
