Abstract

The invention discloses a temperature-controlled intelligent tuned inertial mass damper. The damper is composed of two parts, namely a working cavity temperature control part and a main damper body part. The working cavity temperature control part comprises a temperature monitoring part and a temperature adjusting part. The main damper body part comprises an SMA spring and an inertial mass damperbody connected with the SMA spring through a rack, the rack is connected with a driving gear, the driving gear is in contact with a follow-up flywheel, the follow-up flywheel is connected with a cylinder, and the cylinder is located in a box body filled with viscous liquid. According to the temperature-controlled intelligent tuned inertial mass damper, the inertia force of the damper body can be increased by converting axial motion into rotary motion, and on the premise of ensuring the damping effect, the mass of the damper body is reduced. The damping and stiffness of the SMA spring can alsobe adjusted in real time by changing the temperature, so that the damper body has the stable working performance in a wide frequency domain, and therefore the good damping effect is achieved.

Description

technical field [0001] The invention belongs to the field of vibration control of civil engineering, and in particular relates to a temperature-controlled intelligent tuning inertial vibration damping device, which is mainly used in controlling the vibration response of high-rise buildings and towering structures. technical background [0002] Modern high-rise buildings and towering structures are becoming more and more common with the development and progress of society. Towering structures have low horizontal stiffness, are sensitive to wind loads and earthquakes, and are prone to large dynamic responses. In order to avoid structural damage or even collapse, scholars have paid attention to the safety and stability of towering structures. At the same time, the structure Vibration control technology is also gradually developed. [0003] Mass tuned damping device (Tuned Mass Damper, referred to as "TMD") is to adjust the frequency of the damping device to be similar to the m...
