Problems solved by technology

However, the traditional tuned mass damper has the disadvantage of tuning sensitivity to frequency. Not only the self-damage of the building structure will affect the vibration reduction effect of the tuned mass damper, but sometimes its own characteristics, such as the degradation of the viscous damper Or when a certain component of the building structure is used as the quality of the tuned mass damper, the change of mass will also affect its control effect

Embodiment Construction

[0016] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0017] Such as Figure 1 to Figure 3 As shown, the semi-active pendulum tuned mass damper of the present invention is composed of a pendulum tuned mass damper (2) and a servo control system, and the semiactive pendulum tuned mass damper (2) is installed on the main structure (1) at the top. in:

[0018] The single pendulum tuned mass damper (2) includes a mass block (7), a pendulum rope (8) and a viscous damper (9); when the mass block (7) vibrates horizontally, viscous damping is driven The viscous damper (9) moves to dissipate energy; one end of the viscous damper (9) is connected to the mass block (7), and the other end is connected to the limit device (10).

[0019] The servo control system includes a control circuit board (3), an acceleration sensor I (4), an acceleration sensor II (5) and a stepping motor (6); the accelerati...

Abstract

The invention relates to a semi-active simple pendulum type tuned mass damper, formed by a simple pendulum type tuned mass damper and a servo control system. The simple pendulum type tuned mass damper is formed by a mass block, a swing rope, and a viscous damper. The servo control system is formed by a single-chip microcomputer circuit board, an acceleration sensor I, an acceleration sensor II, and a stepping motor. Length of the swing rope can be adjusted through the servo control system, so as to realize accurate control of frequency of the simple pendulum type tuned mass damper. Compared with the prior art, accurate adjustment of frequency of the semi-active simple pendulum type tuned mass damper can be realized, and damping effect is improved, design of the damper is simplified, and control effect of a damp device is good. The damper is simple in structure, easy in maintenance and installation, and good in endurance.

Description

technical field [0001] The invention belongs to the technical fields of civil engineering and vibration control, in particular to a semi-active single pendulum tuned mass damper. Background technique [0002] In today's society, tuned mass dampers have been widely concerned because of their advantages such as small changes to the original building structure, convenient construction, and significant vibration reduction control effects, and have been used in building structures at home and abroad, such as Taipei 101 Building, Shanghai center etc. However, the traditional tuned mass damper has the disadvantage of tuning sensitivity to frequency. Not only the self-damage of the building structure will affect the vibration reduction effect of the tuned mass damper, but sometimes its own characteristics, such as the degradation of the viscous damper Or when a certain component of the building structure is used as the mass of the tuned mass damper, the change of mass will also aff...
