Ultralow frequency lever tuned mass damper and design method thereof
The invention discloses an ultralow-frequency lever tuned mass damper and a design adjusting method thereof, and relates to the technical field of engineering structure vibration reduction. The lever and the first mass block are fixed on the bottom plate through a spring, and the second mass block is fixed on the bottom plate through a damping device; the two ends of the supporting frame are movably installed on the bottom plate and the lever respectively. The invention further discloses a design method of the ultra-low frequency lever tuned mass damper. The design method comprises the steps that the mass, the design frequency and the damping ratio of a single tuned mass damper, the mass of the two mass blocks and the lengths of the two force arms are sequentially calculated; the tuned mass damper adjusts the position of the supporting frame according to the actually measured frequency of the main structure when the main structure is constructed or used for a certain period of time. According to the ultralow-frequency lever tuned mass damper and the design and adjustment method thereof, the technical problems that a conventional tuned mass damper is long in construction period and poor in vibration reduction effect, and ultralow frequency is greatly limited by installation space are solved.
