Summary: | The invention discloses a simple pendulum type TMD vibration damping device used inside a large wind motor tower-shaped cylinder body. The device comprises top supports, a mass block and viscous dampers. The four top supports are uniformly distributed inside the cylinder body to fix and hang the mass block; the mass block is provided with a bearing ring; a groove is formed in the lower hemisphereof the mass block, so that a steel wire rope can be conveniently wound and suspended; and the four viscous dampers are uniformly distributed below each support, and an axis and a horizontal axis of the bearing ring are on a horizontal line, so that the viscous dampers can dissipate energy and limit the mass block to generate large displacement. When the tower-shaped cylinder body generates shake due to external excitation, the device can generate swing which is always opposite to a structure and generates reaction force on a main structure regardless of the shake generated from any direction by depending on the design |
