Abstract

The invention relates to a vertical viscoelastic collision tuning mass damper device, which comprises a case and a mass block, wherein the case consists of an upper cover plate, a lower cover plate, a left end plate and a right end plate; the mass block is arranged in the case, and comprises a rigid rod in horizontal arrangement, a prismatic mass block arranged in the middle part of the rigid rod, and ball-shaped mass blocks arranged at the two end parts of the rigid rod; viscoelastic materials are symmetrically arranged right above and under the ball-shaped mass blocks; dampers are respectively arranged between the upper cover plate and the upper end surface of the prismatic mass block and between the lower cover plate and the lower end surface of the prismatic mass block; a plurality of springs are also symmetrically arranged on the prismatic mass block and are respectively connected with the upper cover plate and the lower cover plate. The invention also relates to a work mode. The vertical viscoelastic collision tuning mass damper device can realize the passive conversion of different energy-consumption modes under different external excitation.

Description

technical field [0001] The invention relates to a vertical viscoelastic collision tuned mass damper device and its working mode. 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 is based on the phenomenon that the collision process will cause a large amount of energy consumption. 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 parameter ...
