Abstract

The invention discloses a tower device wind tunnel experiment device with a tuned mass damper and an experimental method of the tower device wind tunnel experiment device. The tower device wind tunnel experiment device with the tuned mass damper includes a tower device wind tunnel experiment device body. The body includes a group of round barrels with hollow inner parts, a core beam, a hexagonal prism and a hook. The round barrels are arranged in the axial direction in an overlapping manner. The center of the core beam is provided with a cylinder. The tuned mass damper is arranged above the body. A gap is left between the tuned mass damper and the body. The tuned mass damper includes a mass ring and a steel wire vibration isolator. The steel wire vibration isolator includes a steel wire and a clamp board. The steel wire is fixed on the clamp board in an inserting manner. The mass ring is in threaded connection with the clamp board of the steel wire vibration isolator. The invention has beneficial effects of reasonable structural design, low production cost, convenient operation and experiment and research progress acceleration.

Description

technical field [0001] The invention relates to the technical field of wind tunnel experimental devices for towering equipment, in particular to a wind tunnel experimental device for towering equipment with a tuned mass damper and an experimental method thereof. Background technique [0002] High and flexible structures such as tower equipment and chimneys are very common in petrochemical, chemical, and energy companies. With the rapid development of the petrochemical and energy industries, equipment with high height and high flexibility is increasing, and accidents of towering structures failing due to wind-induced vibration also occur frequently. In petrochemical enterprises in Lanzhou, Shandong, Fujian and other places in my country, there have been accidents in which large-scale tower equipment was induced to vibrate by wind, and the maximum amplitude of the tower top was close to 1.4 meters. Traditional measures for vibration reduction of towering structures include: i...
