Horizontal bidirectional visco elastic collision tuned mass damper system and working method thereof

Abstract

The invention relates to a horizontal bidirectional visco elastic collision tuned mass damper system and a working method thereof. The horizontal bidirectional visco elastic collision tuned mass damper system comprises a hollow circular outer cylinder, an upper cover plate arranged above the hollow circular outer cylinder and a lower cover plate arranged under the hollow circular outer cylinder; a universal joint is arranged in the middle of the lower end surface of the upper cover plate; a circular visco elastic limiting device is arranged in the middle of the upper end surface of the lower cover plate. The horizontal bidirectional visco elastic collision tuned mass damper system further comprises a first cylindrical mass block and a second cylindrical mass block; the circle center part at the upper end of the first cylindrical mass block is hinged to the universal joint through a first rigid rod, and the circle center part at the lower end of the first cylindrical mass block is connected with the circle center part at the upper end of the second cylindrical mass block through a second rigid rod; the lower part of the second cylindrical mass block is positioned in the circular visco elastic limiting device; the first cylindrical mass block is also connected with the inner wall of the hollow circular outer cylinder through a plurality of springs. The horizontal bidirectional visco elastic collision tuned mass damper system provided by the invention is simple in structure and easy to realize and overcomes the defect that the damping effect of a TMD device is very sensitive to the frequency and has poor adaptability to different excitations.

Description

technical field [0001] The invention relates to a horizontal two-way viscoelastic collision tuned mass damper system and a working method thereof. Background technique [0002] As one of the common passive controls, tuned mass damper (TMD) has been widely and maturely used in wind resistance of towering structures in civil engineering and vibration control of pedestrian bridges. However, the TMD device has the inherent defects of non-adjustability and poor adaptability. The vibration reduction effect of the TMD device is very sensitive to frequency and has poor adaptability to different excitations. In view of the deficiencies in the prior art, the present invention will cause a large amount of energy consumption on the basis of the collision process. In the viscoelastic P-TMD damper, a viscoelastic limiting device will be introduced in the traditional TMD device, and the collision will be used to achieve further energy consumption. [0003] Through the reasonable paramete...
