Embodiment 1

[0018] Example 1: Such as Figure 1~4 As shown, the tuned viscous mass damping device includes the rotating mass 2, the ball nut 3 and the inner cylinder 6 as a whole by welding. The ball screw 1 passes through the right end of the ball nut 3 and the inner cylinder 6 in turn, and is clamped with the ball nut through the thread Together; the right end of the outer cylinder 5 and the ball nut 3 are connected by a groove and sealed well, and the two are not connected as a whole by welding; the left end of the outer cylinder 5 and the left end of the inner cylinder 6 are connected by a ball bearing 9; 5 The left end is connected with the tuning spring 4, so that the damper can play the role of a tuning mass damper; the tuning spring 4 is covered with a tuning spring protection tube 8; the right end of the tuning spring protection tube 8 is attached to the left end of the outer tube 5 wall, both Relative misalignment can occur.

Abstract

The invention relates to a tuned viscous mass damping device for energy consumption and vibration reduction of building structures and bridge engineering structures. The damping device includes: a ball screw, a rotating mass, a ball nut, a tuning spring, an outer cylinder, an inner cylinder, stagnant liquids, tuning spring protectors, ball bearings and earrings. The rotating mass, the ball nut, and the inner cylinder are connected as a whole by welding; the ball screw passes through the ball nut and the right end of the inner cylinder in turn, and is restrained with the ball nut through threads; the inner cylinder and the outer cylinder are filled with viscous liquid. The invention can simultaneously play the roles of the tuning mass damper and the nonlinear viscous damper, and produces viscous damping efficiency and mass efficiency through the ball screw, and has excellent energy consumption performance.

Description

Technical field [0001] The invention belongs to the technical field of energy dissipation and damping of civil engineering structures, and relates to a tuned viscous mass damper. Background technique [0002] The traditional method of damping the building construction is to increase the cross section of the components and increase the reinforcement to resist. The result is that the larger the cross section, the greater the stiffness, and the greater the seismic effect. It is not only difficult to ensure safety, but also greatly increases the cost of the project. , The introduction of vibration control technology has solved this problem. Energy dissipation and vibration reduction technology, as a passive structural vibration reduction control technology, has been gradually applied to buildings or structures in recent years. The so-called energy dissipation and vibration reduction technology is to add energy dissipation and vibration reduction devices to the structure, and the add...
